DETAILED DESCRIPTION
[0045] In the following, only some possible embodiments of the disclosure are described in detail. However, the present disclosure is not limited to these, and a multitude of other embodiments are applicable without departing from the scope of the disclosure. It is to be understood that these exemplary embodiments can be modified in a number of ways and combined with each other whenever compatible and that certain features may be omitted in so far as they appear dispensable. In particular, the disclosed embodiments may be modified by combining certain features of one embodiment with one or more features of another embodiment.
[0046] The present disclosure relates to rockers points and rocker point adjustment elements arranged in a shoe. A rocker point is a point on a sole of a shoe at which a load on the foot of the wearer transitions from one region of the foot to another. In some embodiments, a shoe can have one rocker point (for example, when the load on the foot of the wearer transitions from the midfoot to the forefoot. In some embodiments, a shoe can have two rocker points. For example, a shoe can have a first rocker point where the load transitions from the rearfoot to the midfoot, and another rocker point where the load transitions from the midfoot to the forefoot. In some embodiments, a shoe can have more than two rocker points to define additional transition points during the walking or running gait of the wearer.
[0047] The present disclosure relates to a rocker point adjustment element adapted to be arranged in a shoe. In some embodiments, the rocker point adjustment element may comprise at least one segment and means for guiding the at least one segment. Further, the means for guiding may be configured to guide the at least one segment along a path such that the at least one segment is movable along the path, wherein guiding the at least one segment along the path guides and/or moves a respective rocker point of the shoe along the path.
[0048] In some embodiments, the rocker point adjustment element may comprise at least one segment and means for guiding the at least one segment. Guiding the at least one segment may comprise confining the movability of the at least one segment with respect to at least one direction. The at least one segment and the means for guiding may be connected. Generally, the means for guiding may be configured to guide the at least one segment along a path such that the at least one segment is movable along the path. The path may be based on the means for guiding and/or the at least one segment. For example, the path may be based on a geometry of the means for guiding.
[0049] In some embodiments, guiding the at least one segment along the path may guide and/or move a respective rocker point of the shoe along the path. In other words, when the segment is guided and/or moved along the path, a respective rocker point of the shoe may be guided and/or moved along the path. In general, there may be an association between a position of the at least one segment and the rocker point of the shoe. For example, by moving the at least one segment along the path, the respective rocker point of the shoe may move along the path. In particular, moving the at least one segment along the path may result in a corresponding movement of the respective rocker point along the path. In some embodiments, moving the at least one segment along the path may not translate in a corresponding movement of the respective rocker point along the path. For example, the movement of the respective rocker point of the shoe may be based on a projection of the path with respect to an axis. The rocker point of the shoe may refer to a particular point and/or to a particular axis. In addition, the rocker point may be associated with an area of the shoe, preferably wherein the area comprises an axis associated with the rocker point of the shoe.
[0050] In some embodiments, guiding the at least one segment along the path such that a respective rocker point of the shoe is guided and/or moved along the path may allow the respective rocker point of the shoe to change. For example, it may allow the respective rocker point of the shoe to change from a first position to a second position. In particular, the rocker point of the shoe may be adjusted according to the needs and demands of an individual athlete, thereby resulting in a measurable performance benefit for the athlete. Consequently, the rocker point of the shoe may be adapted to the athlete, maximizing the performance and optimizing the wearing comfort.
[0051] In some embodiments, a subset of the at least one segment may be moved together as a group. For example, the subset of the at least one segment may be moved as a group between the neighboring segments to adjust the rocker point of the shoe. Specifically, the subset of the at least one segment may comprise at least two segments of the rocker point adjustment element. Moving the subset of segments as a group may mean that the segments in the subset are moved by the same amount along the path. In some embodiments, the segments in the subset may be connected to each other such that moving one segment from the subset induces a movement of the remaining segments in the subset. In some embodiments, the connection between the segments may comprise a permanent or a reversible connection. For example, using a reversible connection may allow the athlete to reconfigure and/or exchange the segments within the subset. Generally, the rocker point adjustment element may comprise a first subset of segments that are moved as a first group to adjust a first rocker point of the shoe and a second subset of segments that are moved as a second group to adjust a second rocker point of the shoe. In particular, the first rocker point may comprise a rearfoot rocker point and the second rocker point may comprise a forefoot rocker point.
[0052] In particular, the path may be essentially along a longitudinal direction of the shoe. A longitudinal direction of the shoe may be any direction extending from a portion of the shoe adapted to receive a rearfoot to a portion of the shoe adapted to receive a forefoot. For example, the longitudinal direction of the shoe may be associated with a longitudinal direction of a foot. In particular, the longitudinal direction of the foot may be associated with a foot length, e.g., the longitudinal direction of the foot may be the direction used for measuring a length of the foot (for example, along a longitudinal axis of the foot).
[0053] The means for guiding the at least one segment may be configured to guide the at least one segment along a longitudinal direction of the shoe. For example, the shape and/or geometry of the means for guiding may be based on the longitudinal direction of the shoe. In particular, the means for guiding may extend in the longitudinal direction of the shoe (for example, the longitudinal axis of the shoe).
[0054] Generally, the means for guiding of the rocker point adjustment element may be configured such that moving the at least one segment along the path comprises an essentially linear motion.
[0055] Moving the at least one segment along the path in an essentially linear motion may mean that the motion is essentially along one direction. A motion along essentially one direction may mean that there exists a direction such that a projection of the motion onto the direction comprises at least 50% of the motion, at least 70% of the motion, or at least 90% of the motion. In addition, or alternatively, an essentially linear motion may comprise that the motion trajectory has a bounded curvature. For example, an essentially linear motion may at least not comprise at least a part of a rotation. In general, an essentially linear motion may be based on a translation.
[0056] In some embodiments, moving the at least one segment along the path may comprise at least partly a torsion of the at least one segment. For example, the at least one segment may be movable in an essentially linear motion and may be movable in an essentially linear motion in a direction not parallel to a longitudinal direction of the shoe. Being movable in a direction not parallel to a longitudinal direction of the shoe may mean that a first portion of the at least one segment may be moved in a first direction by a first amount and that a second portion of the at least one segment may be moved in a second direction by a second amount. Specifically, the first direction may be essentially opposite to the second direction. For example, the first and/or second portion of the at least one segment may be associated with a medial and/or lateral portion of the at least one segment. Moving the first portion of the at least one segment in a first direction by a first amount and the second portion of the at least one segment in a second direction by a second amount may induce a torsion of the at least one segment. Inducing a torsion of the at least one segment may change the rocker point of the shoe from a first position to a second position.
[0057] In some embodiments, the at least one segment may be moved in an essentially linear motion along a path which is essentially along a longitudinal direction of the shoe. For example, the at least one segment may be moved from a first position along a longitudinal direction of the shoe to a second position in an essentially linear motion.
[0058] Moving the at least one segment along the path in an essentially linear motion, such as in a longitudinal direction of the shoe, may allow for moving the respective rocker point of the shoe in an essentially linear motion along the path. This linear motion may result in a measurable and/or substantial change of the rocker point of the shoe, thereby generating a measurable performance benefit for the athlete.
[0059] In some embodiments, the at least one segment may comprise block foam and/or particle foam. In addition, or alternatively, the at least one segment may comprise a material based on polymers, for example polyamide and/or polyurethane and/or co-polyester, and/or rubber blends and/or ethylene-vinyl acetate.
[0060] In some embodiments, the at least one segment may be separated from neighboring segments by gaps. For example, the at least one segment may be separated from neighboring segments such that the means for guiding is configured to guide the at least one segment between the neighboring segments.
[0061] Separating the at least one segment from neighboring segments by gaps may mean that a distance between the neighboring segments is larger than an extension and/or elongation and/or width of the at least one segment. In some embodiments, the size of the gaps may be based on a difference between the distance between the neighboring segments and the extension and/or elongation of the at least one segment. Generally, a gap may refer to a portion of the rocker point adjustment element which does not comprise the at least one segment. In particular, a gap may refer to a portion of the rocker point adjustment element which does not comprise a part of the at least one segment. For example, the gap may comprise at least a part of the means for guiding without comprising the at least one segment. In particular, the gap may comprise at least a part of a plate/frame/reinforcing element and/or at least a part of at least one rod.
[0062] In some embodiments, moving the at least one segment along the path may be based on the separation of the at least one segment from the neighboring segments. For example, the size of the gaps may at least partially bound and/or confine the motion of the at least one segment.
[0063] In some embodiments, the at least one segment may be separated from the neighboring segments such that the means for guiding is configured to guide the at least one segment between the neighboring segments. For example, the means for guiding may be configured to guide the at least one segment from a first position in a vicinity of the a first neighboring segment to a second position in a vicinity of a second neighboring segment. Guiding the at least one segment may be bounded and/or confined based on the neighboring segments. For example, the at least one segment may be guided in an essentially linear motion from the first position to the second position (for example, from the first neighboring segment to the second neighboring segment) along a longitudinal axis of the shoe.
[0064] Separating the at least one segment from neighboring segments by gaps may allow the at least one segment to move between the neighboring segments, thereby enabling the respective rocker point to be moved between the neighboring segments. Therefore, the respective rocker point may be adapted to the needs and the demands of an individual athlete and therefore may result in a measurable performance benefit.
[0065] In some embodiments, the at least one segment may be a block extending from a medial side of the shoe to a lateral side of the shoe. Specifically, the block may be a continuous block extending from the medial side of the shoe to the lateral side of the shoe. For example, the block may comprise an essentially rectangular block. An essentially rectangular block may comprise a rectangular block, wherein the edges may comprise a curvature. Using a block extending from the medial side to the lateral side of the shoe as a segment may allow for an accurate and easy adjustment of the rocker point of the shoe. For example, if at least two blocks are used, the blocks and/or the segments may be spaced apart in a longitudinal direction.
[0066] In some embodiments, the rocker point adjustment element may comprise at least one segment which is separated from other segments in a longitudinal and a transverse direction. In particular, the rocker point adjustment element may comprise at least one segment which does not extend continuously from the medial side to the lateral side of the shoe. For example, there may be gaps between segments with respect to a direction extending from the medial side to the lateral side of the shoe (e.g., the transverse direction). In other words, the segment may be not a continuous block extending from the medial side to the lateral side of the shoe, but the segment may comprise at least two subsegments, wherein the subsegments are separated with respect to the transverse direction. For example, the rocker point adjustment element may comprise a first segment movable along a first path and a second segment movable along a second path, wherein the first segment and the second segment are spaced apart in a longitudinal direction and a transverse direction. In some embodiments, there may be a first segment associated with a lateral side of the shoe and a second segment associated with a medial side of the shoe. In some embodiments, the first segment and the second segment may be movable independently.
[0067] In some embodiments, the edges of the at least one segment may comprise bevels and/or may be rounded off.
[0068] In some embodiments, at least one edge of the at least one segment may comprise bevels and/or may be rounded off. In an example embodiment in which the at least one segment comprises a shape of a rectangular cuboid, at least a part of the twelve edges of the rectangular cuboid may comprise bevels and/or may be rounded off. For example, when the at least one segment comprises block foam and/or particle foam, at least one edge of the at least one segment may comprise bevels and/or is rounded off.
[0069] Equipping at least a part of the edges of the at least one segment with bevels and/or rounding them off may limit or reduce instances in which the at least one segment comprises sharp edges. In particular, it may limit or reduce instances in which a segment comprising block foam and/or particle foam, e.g., ethylene-vinyl acetate, comprises sharp edges. In particular, when the at least one segment is injection molded and/or 3D printed sharp edges may damage neighboring segments and thereby reduce the lifespan of the shoe comprising the rocker point adjustment element. In some embodiments, the edges of the at least one segment may be beveled and/or rounded if the at least one segment is injection molded and/or 3D printed. Generally, sharp edges may harm the athlete when handling and/or putting on the shoe. In addition, beveled and/or rounded edges may facilitate a smoother transition between the segments and the gaps when the shoe touches the ground. For example, beveled and/or rounded edges may reduce and/or remove a crunching and/or jarring of the segments when the shoe is in use. Thereby, beveled and/or rounded edges may contribute to the wearing comfort of the athlete.
[0070] In some embodiments, the means for guiding may be an internal reinforcement element, for example at least one rod and/or plate. In particular, the at least one rod and/or plate may be stiff.
[0071] In some embodiments, the internal reinforcement element may be an element adapted to improve the stability and/or physical properties of the shoe. For example, the internal reinforcement element may be at least partially located in a midsole of the shoe. In addition, or alternatively, the internal reinforcement element may comprise at least a part of the rocker point adjustment element.
[0072] In some embodiments, the internal reinforcement element may be at least a rod and/or a plate. For example, a rod may be an element that essentially extends in one direction and/or along a path. A plate may be an element that essentially extends in two directions and/or is essentially described by a surface. In particular, the surface may comprise a curvature, e.g., the surface may not be planar. In some embodiments, the internal reinforcement element may comprise multiple rods. For example, the multiple rods may be arranged such as to cover the shoe uniformly. Covering the shoe uniformly may comprise that a transverse distance between the multiple rods (for example, a distance between rods in a medial-lateral direction) is essentially equal (for example, within ten percent of being equal). In some embodiments, the internal reinforcement may comprise a plate. For example, the plate may essentially follow the form and/or the shape of the shoe, such as the form and/or the shape of the midsole of the shoe.
[0073] In some embodiments, the rods and/or the plate may be stiff. In some embodiments, being stiff may indicate that the rods and/or the plate are stiffer than the at least one segment. In particular, the rods and/or plate may be stiffer than the at least one segment comprising block foam and/or particle foam. In addition, or alternatively, being stiff may indicate that the at least one segment is stiffer than the rods and/or the plate. In some embodiments, the stiffness of the rods may be different. For example, a first rod may comprise a first stiffness and a second rod may comprise a second stiffness. In addition, or alternatively, the stiffness of the rods may be the same. In some embodiments, the stiffness of the plate may comprise a spatial dependence. For example, a first region of the plate may comprise a first stiffness and a second region of the plate may comprise a second stiffness. For example, a stiffness of the plate on the lateral side may be different from a stiffness of the plate on a medial side. As another example, a stiffness of the plate in a forefoot region may be different from a stiffness of the plate in a rearfoot region.
[0074] In some embodiments, the stiffness of the rods and/or plates may comprise a bending stiffness and/or a tensile stiffness. For example, the stiffness may comprise a bending stiffness. In particular, the bending stiffness of the rods and/or the plate may be configured so as to offer the necessary bending stiffness needed during a run. In some embodiments, the bending stiffness of the rods and/or plate may be lower than a tensile stiffness of the rods and/or plate.
[0075] Using a stiff internal reinforcement element as means for guiding, e.g., rods and/or a plate, may allow the at least one segment to be guided and/or moved along the path, thereby moving the respective rocker point of the shoe along the path. Therefore, the respective rocker point may be adapted to the needs and the demands of an individual athlete and therefore may result in a measurable performance benefit.
[0076] In some embodiments, the means for guiding may comprise position indications. A position indication may comprise any visible indication on the means for guiding from which a position of the at least one segment relative to the means for guiding and/or relative to neighboring segments and/or relative to the rocker point adjustment element may be deduced. Specifically, a position indication may allow an observer (for example, the wearer) to deduce a distance between the at least one element and the neighboring elements. In addition, or alternatively, if the at least one segment comprises a first and a second segment, the position indications may indicate a distance between the first and second segment. For example, position indications may comprise markings and/or rings on the means for guiding. In particular, the rods and/or the plate may comprise markings and/or rings. For example, if the rocker point adjustment element comprises rods, at least one of the outermost rods, e.g., the most lateral rod and/or the most medial rod, may comprise position indications. In some embodiments, all rods may comprise position indications. Position indications on the means for guiding may help the user of the rocker point adjustment element to precisely adjust the at least one segment and thereby precisely adjust the rocker point of the shoe.
[0077] In some embodiments, at least a part of the internal reinforcement element may extend through the at least one segment. In particular, at least part of the internal reinforcement element may extend through the at least one segment such that the path corresponds to an elongation path of the internal reinforcement element.
[0078] In some embodiments, at least a part of the internal reinforcement element extending through the at least one segment may indicate that at least a part of the internal reinforcement element is at least partially surrounded by the at least one segment. For example, the at least one segment may comprise at least one aperture or channel through which the internal reinforcement element extends. In particular, if the internal reinforcement element comprises rods, the at least one segment may comprise at least one aperture or channel, for example based on a shape and/or a cross-section of the rods, through which the rods extend. In some embodiments, the number of apertures may be based on the number of rods. In embodiments in which the internal reinforcement element comprises a plate, the at least one segment of foam may comprise an aperture or channel which is based on a shape and/or a cross-section of the plate.
[0079] In some embodiments, the internal reinforcement element may extend through the at least one segment such that the path corresponds to an elongation path of the internal reinforcement element. For example, the aperture may be configured so as to enable the at least one segment to be guided and/or moved along the path. In particular, the size of the aperture or channel may be larger than the size of the cross-section of the rods and/or the plate in order to ensure that the at least one segment can be guided and/or moved along the path. Generally, the shape of the rods and/or the plate may be such that the corresponding direction of elongation is associated with an elongation direction of the shoe. For example, the rods and/or the plate may extend in a longitudinal direction of the shoe.
[0080] In general, the at least one segment may be configured such that a transverse projection of the at least one segment with respect to the longitudinal axis of the shoe comprises an essentially continuous segment.
[0081] A transverse projection of the at least one segment with respect to the longitudinal axis of the shoe may comprise a view of the at least one segment and/or the shoe from a lateral side and/or a medial side. For example, the transverse projection may comprise a view of the shoe and/or the at least one segment in a plane comprising the means for guiding.
[0082] An essentially continuous segment may mean that the segment is smoothly connected. In some embodiments, the essentially continuous segment may not comprise a gap.
[0083] In some embodiments, the transverse projection of the at least one segment with respect to the longitudinal axis of the shoe comprising an essentially continuous segment may mean that a lateral and/or medial side view of the at least one segment and/or the shoe does not display gaps with respect to the at least one segment which extend from the medial side to the lateral side and/or from the lateral side to the medial side.
[0084] For example, if the at least one segment is separated from neighboring segments by gaps, the at least one segment may be configured such that a lateral and/or medial side view of the at least one segment and/or shoe does not display gaps with respect to the at least one segment which extend from the medial side to the lateral side and/or from the lateral side to the medial side. In particular, the at least one segment and/or the neighboring segments may comprise an interlocking geometry. The interlocking geometry may be configured so as to enable the at least one segment to be guided and/or moved between the neighboring segments. For example, the at least one segment may comprise protrusions on sides that are adjacent to the neighboring segments. In addition, or alternatively, the neighboring segments may comprise apertures that are configured to receive at least a part of the protrusions. For example, the geometry and/or size of the apertures may be based on the geometry and/or size of the protrusions. In some embodiments, the protrusions of the at least one segment may extend at least partially into the apertures independent of the position of the at least one segment, thereby ensuring that the transverse projection of the at least one segment with respect to the longitudinal axis of the shoe comprises an essentially continuous segment.
[0085] In some embodiments, the segment may comprise an essentially continuous segment even though a gap between the segment and at least one neighboring segment exists. For example, the gap may still exist, but if the shoe and/or the rocker point adjustment element is viewed from the medial side, one cannot look through the shoe and/or rocker point adjustment element towards the lateral side. In other words, the neighboring segments are separated by a gap, but they interlock such that one cannot see through the gap. For example, interlocking the segment and the neighboring segment may be achieved by a non-straight gap, e.g., a curved gap and/or a dent/notch in the segments. In particular, the curved gap and/or the dents and/or notches in the segments may obstruct the view from the lateral side towards the medial side of the shoe.
[0086] In some embodiments, the wearer may not recognize and/or feel the gap when wearing the shoe with the essentially continuous segment. In particular, the essentially continuous segment may contribute to a smooth transition between the segments such that the wearer perceives no unusual interruptions in the sole.
[0087] In some embodiments, the at least one segment may be moveable backward with respect to the path. In addition, or alternatively, the at least one segment may be moveable forward with respect to the path.
[0088] In some embodiments, the at least one segment may be movable backward with respect to the path. Backward may refer to a direction based on a portion of the shoe which is adapted to receive a backfoot or rearfoot. Similarly, forward may refer to a direction based on a portion of the shoe which is adapted to receive a forefoot. For example, the at least one segment may be movable backward and/or forward along the path wherein the path is essentially along a longitudinal direction (for example, a forefoot-rearfoot direction) of the shoe. In addition, or alternatively, the at least one segment may be movable backward and/or forward with respect to the path such that moving the at least one segment along the path comprises an essentially linear motion.
[0089] Enabling the at least one segment to be movable backward and/or forward with respect to the path may enable the respective rocker point of the shoe to be movable backward and/or forward with respect to the path. In particular, the respective rocker point may be first moved forward with respect to a longitudinal direction of the shoe and afterwards be moved backwards, or vice versa. Therefore, the respective rocker point may be movable in forward and/or backward direction, which may allow for a correction of a miss-adjustment of the rocker point. In particular, it may allow for a precise adjustment of the rocker point as the optimal rocker point may be reached in an iterative process of moving the rocker point forward and/or backward. Thus, the respective rocker point may be adapted precisely to the needs and the demands of an individual athlete and therefore may result in a maximal performance benefit.
[0090] In some embodiments, the at least one segment may be moveable along the path by an amount of at least 2 mm, at least 5 mm, or at least 8 mm. In addition, the at least one segment may be movable along the path by an amount of at most 30 mm, at most 20 mm, or at most 10 mm. Generally, the size of the gaps and/or the size of the segments and/or the length of the path may depend on a size of the shoe. For example, the size of the gaps and/or the size of the segments and/or the length of the path may be in correspondence with a shoe size measurement (for example, a shoe size measured in US units, UK units, or other units, such as a shoe size measured in barleycorns).
[0091] That the at least one segment is movable along the path by an amount of at least 2 mm, at least 5 mm, or at least 8 mm may enable the at least one segment to be moved along the path by an amount of at least 2 mm, at least 5 mm, or at least 8 mm. For example, the at least one segment and the neighboring segments may be configured such that the at least one segment is movable along the path by an amount of at least 2 mm, at least 5 mm, or at least 8 mm. In particular, the gaps between the at least one segment and the neighboring segments may have a size such that the at least one segment is movable along the path by an amount of at least 2 mm, at least 5 mm, or at least 8 mm. That the at least one segment is movable along the path by an amount of at least 2 mm, at least 5 mm, or at least 8 mm may allow for moving the respective rocker point of the shoe by an amount of at least 2 mm, at least 5 mm, or at least 8 mm. This may ensure that the respective rocker point of the shoe can be changed by a sufficient amount such that the individual needs and demands of an athlete can be taken into account. In other words, that the at least one segment is movable along the path by an amount of at least 2 mm, at least 5 mm, or at least 8 mm may ensure a sufficient flexibility of the respective rocker point of the shoe.
[0092] In some embodiments, the at least one segment may be movable along the path by an amount of at most 20 mm. For example, the at least one segment and the neighboring segments may be configured such that the movement of the at least one segment is confined to an amount of at most 20 mm. Confining the movement of the at least one segment to at most 20 mm may confine the size and/or the shape of the gaps between the at least one segment and the neighboring segments. Therefore, a sufficient stability of the shoe may be provided while, at the same time, ensuring a sufficient flexibility of the respective rocker point of the shoe. In particular, a smooth-running experience of the athlete can be provided.
[0093] In some embodiments, the at least one segment may be arranged in a portion of the shoe which is adapted to receive a forefoot. In addition, or alternatively, the at least one segment may be arranged in a portion of the shoe which is adapted to receive a rearfoot.
[0094] In some embodiments, arranging the at least one segment in a portion of the shoe that is adapted to receive a forefoot may comprise receiving the at least one segment in a portion of the shoe that is associated with at most 50% of a front portion of the foot, at most 45% of a front portion of the foot, or at most 40% of a front portion of a foot. For example, the at least one segment may be configured such that it is movable within a region associated with a forefoot. Arranging the at least one segment in a portion of the shoe that is adapted to receive a forefoot may allow movement of a respective rocker point of the shoe within a portion of the shoe associated with the forefoot. In addition, or alternatively, the at least one segment may be arranged in a portion of the shoe which is adapted to receive a rearfoot, and may allow movement of a respective rocker point of the shoe within a portion of the shoe associated with the rearfoot. In some embodiments, there may be at least one segment arranged in a portion of the shoe which is adapted to receive a forefoot and another at least one segment arranged in a portion of the shoe which is adapted to receive a rearfoot. For example, moving the at least one segment arranged in the forefoot portion and the at least one segment arranged in the rearfoot portion may jointly contribute to moving a respective rocker point of the shoe.
[0095] In some embodiments, a shoe may comprise multiple rocker points. For example, the shoe may comprise a rearfoot rocker point and/or a forefoot rocker point. Consequently, it may be desirable to individually adjust the rearfoot rocker point and the forefoot rocker point. For example, the at least one segment in a portion of the shoe that is adapted to receive a forefoot may be configured to adjust the forefoot rocker point of the shoe. In particular, moving the at least one segment arranged in the portion of the shoe that is adapted to receive the forefoot may move the corresponding forefoot rocker point. Similarly, the at least one segment arranged in a portion of the shoe that is adapted to receive a rearfoot may be configured to adjust the rearfoot rocker point of the shoe. In particular, moving the at least one segment arranged in the portion of the shoe that is adapted to receive the rearfoot may move the corresponding rearfoot rocker point. In some embodiments, the segments in the portion of the shoe adapted to receive the forefoot may be adjustable independently of the segments in the portion of the shoe adapted to receive the rearfoot. Thereby, the forefoot rocker point of the shoe may be adjusted independently of the rearfoot rocker point of the shoe. By adjusting the rearfoot rocker point and the forefoot rocker point independently the shoe may be customized to the individual needs of the athlete, thus contributing to an optimal performance.
[0096] In some embodiments, the rocker point adjustment element may further comprise means for fixing the at least one segment. The means for fixing may be configured to fix the at least one segment at a respective first position.
[0097] Fixing the at least one segment by the means for fixing may restrict movement of the at least one segment along the path. For example, the at least one segment may be fixed with respect to a respective first position. In some embodiments, the respective first position may be a position with respect to the means for guiding. Fixing the at least one segment ensures that the at least one segment remains at the respective first position. For example, fixing the at least one segment at the first position may ensure that during usage of the shoe the at least one segment remains at the first position. Generally, fixing the at least one segment may comprise coupling the at least one segment to the means for guiding such that the at least one segment becomes fixed with respect to the means for guiding. In particular, the means for fixing may couple the at least one segment to the means for guiding.
[0098] In some embodiments, fixing the at least one segment at the respective first position may fix a respective first rocker point of the shoe. For example, the at least one segment may have initially been moved to the respective first position to move and/or to change a respective rocker point of the shoe. After adjusting the respective rocker point of the shoe to the individual needs and demands of the athlete, the at least one segment may be fixed at the respective first position, thereby fixing a respective first rocker point of the shoe. In some embodiments, the respective first rocker point may be a rocker point which the individual athlete prefers.
[0099] In some embodiments, the means for fixing may be unfastened such that the at least one segment can be moved along the path to a respective second position.
[0100] Unfastening the means for fixing may allow movement of the at least one segment along the path after the at least one segment was initially fixed by the means for fixing. For example, unfastening may comprise decoupling the at least one segment from the means for guiding, for example by removing or loosening the means for fixing. Moving the at least one segment from the first position to the second position may allow to move a respective rocker point of the shoe from a first position to a second position. For example, the first rocker point may have been the preferred rocker point for an individual athlete at a first time, while the second rocker point may be the preferred rocker point for the individual athlete at a second time. Therefore, unfastening the at least one segment may allow for readjustment of the respective rocker point of the shoe to the current needs and demands of the individual athlete. Consequently, an optimal and measurable performance benefit can be provided.
[0101] In some embodiments, the means for fixing may comprise a mechanical fastening mechanism, for example, a clamping and/or locking mechanism. Particularly, the mechanical fastening mechanism may comprise at least one screw and/or nut and/or bolt. In addition, or alternatively, the mechanical fastening mechanism may comprise nails and/or rivets and/or pins. In some embodiments, the mechanical fastening mechanisms may be configured so as to offer a permanent fixation of the rocker points of the shoe. In some embodiments, the mechanical fastening mechanisms may be configured so as to offer a reversible fixation of the rocker points of the shoe, e.g., mechanical fastening mechanism may be unfastened.
[0102] Using a mechanical fastening mechanism may ensure that the at least one segment is fastened such that it cannot be unfastened, unintentionally, during usage of the shoe. Furthermore, using a mechanical fastening mechanism may enable the means for fixing to be unfastened, intentionally, such that the at least one segment can be moved along the path to a respective second position. In some embodiments, the at least one screw may be a sunken screw.
[0103] In some embodiments, the means for fixing may comprise a glue, for example a fast-curing glue. In addition, or alternatively, the means for fixing may be based on a pin/hole locking system. For example, there may be at least one pin extending from the means for guiding, preferably on the lateral and/or the medial side of the means for guiding. In particular, the at least one pin may be movable by pressing the at least one pin into a direction pointing to a center of the means for guiding the at least one segment such that the at least one segment can be moved along the path. More specifically, the at least one pin may be spring-loaded such that the at least one pin automatically extends into a corresponding hole when the at least one pin is aligned with the corresponding hole.
[0104] In some embodiments, the mechanical fastening mechanism may comprise at least one fixing element adapted to be inserted between the at least one segment and at least one neighboring segment.
[0105] Inserting the at least one fixing element between the at least one segment and at least one neighboring segment may fix (e.g., limit movement of) the at least one segment. For example, the at least one segment may be fixed due to friction between the at least one fixing element, the means for guiding, the at least one segment, and the neighboring segments. In particular, the number of fixing elements may be based on the number of segments. For example, there may be one fixing element associated with each of the at least one segment. In addition, or alternatively, there may be two fixing elements associated with each of the at least one segment. In some embodiments, the number of fixing elements associated with different segments may be different. For example, there may be a first number of fixing elements associated with a first segment and a second number of fixing elements associated with a second segment, wherein the first number and the second number may be different. In some embodiments, the at least one fixing element may comprise the same material as the at least one segment and/or the neighboring segments. In some embodiments, the at least one fixing element may comprise and the at least one segment and/or the neighboring segments may comprise different materials. In some embodiments, the number of fixing elements may be based on the number of gaps between the segments.
[0106] In some embodiments, the size of the at least one fixing element may be configured to fix the at least one segment at a first position. For example, the at least one fixing element may comprise a structure which is compatible with the means for guiding.
[0107] In some embodiments, the size of the at least one fixing element may be based on the size of the gaps between the at least one segment and the neighboring segments. For example, the at least one fixing element may be fixed via two fixing elements such that the total size of the two fixing elements corresponds to the total size of the gaps between the at least one segment and the neighboring segments. In some embodiments, the at least one fixing element may be configured to fix the at least one segment at a first position. For example, the first position may correspond to a first respective rocker point of the shoe, wherein the first respective rocker point of the shoe is a preferred rocker point with respect to an individual athlete.
[0108] In some embodiments, the size and/or the shape of the at least one fixing element may be adapted to fix the at least one segment at the first position. For example, a first fixing element may have a first size and a second fixing element may have a second size, wherein the size of the first fixing element and the size of the second fixing element are configured so as to fix the at least one segment at the first position. In some embodiments, the first fixing element may be smaller than the second fixing element, which may allow the at least one segment to be fixed at a position closer to a rearfoot part of the shoe. In some embodiments, the first fixing element may be larger than the second fixing element, which may allow the at least one segment to be fixed at a position closer to a forefoot portion of the shoe. In addition, or alternatively, the position of the first fixing element may be configured to fix the at least one segment at the first position.
[0109] In some embodiments, a structure which is compatible with the means for guiding may enable the at least one fixing element to be inserted between the at least one segment and at least one neighboring segment. In some embodiments, a compatible structure may comprise a structure that is complementary to a structure of the means for guiding. For example, the compatible structure may comprise at least one aperture or channel, wherein the aperture or channel corresponds to a geometry of the means for guiding. In particular, if the means for guiding comprises rods, the at least one fixing element may comprise apertures or channels configured to receive at least a part of the rods when being inserted between the at least one segment and at least one neighboring segment. In addition, or alternatively, the at least one fixing element may comprise teeth and/or at least one comb. For example, the teeth and/or the at least one comb may be configured such that the rods can pass between the teeth.
[0110] In some embodiments, the adjustment of the rocker point of the shoe may comprise a remote adjustment of the rocker point of the shoe. For example, the remote adjustment of the rocker point of the shoe may comprise a remote adjustment of the at least one segment of the rocker point adjustment element. Specifically, the remote adjustment of the rocker point may comprise remotely adjusting the rocker point via a wireless connection and/or an electronic connection. For example, the rocker point adjustment element may be configured to access a wireless network and/or to connect with an electronic device. In some embodiments, the rocker point adjustment element may be configured to connect via a Bluetooth connection to an electronic device and/or a network. For example, the electronic device may be a portable electronic device, e.g., a mobile phone and/or a tablet computer and/or a smart watch.
[0111] In some embodiments, the remote adjustment of the rocker point may involve at least one sensor. The sensor may comprise a sensor adapted to measure a ground contact time of the shoe and/or the rocker point adjustment element. For example, the rocker point adjustment element may comprise at least one sensor. In addition, or alternatively, the at least one sensor may be configured to detect a location of the rocker point of the shoe and/or the at least one segment of the rocker point adjustment element. In some embodiments, the at least one sensor may be configured to detect the position of each of the at least one segments of the shoe. For example, the at least one sensor may be configured to detect a position of a forefoot rocker point of the shoe and/or a rearfoot rocker point of the shoe. In particular, the at least one sensor may detect a position of a segment in a portion of the shoe adapted to receive a forefoot and/or to detect a position of a segment in a portion adapted to receive a rearfoot.
[0112] In some embodiments, the rocker point adjustment element may further comprise means for automatically adjusting the rocker point of the shoe. For example, the rocker point adjustment element may comprise means for automatically adjusting a position of the at least one segment of the rocker point adjustment element. Specifically, the means for automatically adjusting may comprise mechanical means for adjusting the rocker point of the shoe. Specifically, the means for automatically adjusting may comprise a motor, e.g., an electric motor. For example, the means for automatically adjusting may comprise a linear motor and/or a rotational motor. In particular, the rotational motor may be adapted so as to translate a rotational movement into a linear movement, e.g., into a linear movement of the at least one segment of the rocker point adjustment element. In some embodiments, the rotational movement may be translated into a linear movement based on a lead screw. Specifically, the lead screw may comprise a buttress thread and/or a round thread and/or a square thread. In addition, or alternatively, the mechanical means may comprise a screw. In particular, the mechanical means may comprise an elongated screw extending through the at least one segment. For example, the mechanical means for adjusting (e.g., the screw and/or elongated screw) may be configured such that rotating the screw and/or elongated screw induces a movement of the at least one segment. In some embodiments, the means for automatically adjusting may be connected to the at least one sensor. In general, the means for automatically adjusting may be adapted to automatically adjust the rocker point during a race.
[0113] In some embodiments, the at least one sensor may be adapted to detect and/or to measure a running speed. Specifically, the means for automatically adjusting the rocker point may be adapted to adjust the rocker point based on the running speed, e.g., the running speed detected and/or measured by the at least one sensor. For example, the means for adjusting may be configured so as to move the rocker point rearward (e.g., toward a rearfoot portion) when the running speed increases. In other words, the faster the running speed, the further rearward the means for automatically adjusting may move the rocker point. In some embodiments, moving the rocker point further rearward may comprise moving at least one segment closer to a region adapted to receive a rearfoot.
[0114] In some embodiments, the at least one sensor may be adapted to detect and/or to measure a flight phase duration. Specifically, the flight phase duration may comprise a duration between impacts of the shoe with the ground and/or of the foot of the athlete with the ground, e.g., between consecutive impacts of the shoe with the ground and/or of the foot of the athlete with the ground. For example, the means for automatically adjusting may be configured to adjust the rocker point based on the flight phase duration.
[0115] In some embodiments, the at least one sensor may be configured to detect and/or to measure a slope and/or inclination. For example, the at least one sensor may be configured to detect and/or measure a slope and/or inclination of the shoe and/or the foot of the athlete. Generally, detecting and/or measuring the slope and/or inclination may be based on a goniometer. Specifically, the at least one sensor, such as a goniometer, may be arranged at the shoe. For example, the least one sensor, such as the goniometer, may be arranged at the midsole and/or in the midsole, e.g., arranged within the midsole. In addition, or alternatively, the at least one sensor, such as the goniometer, may be arranged at and/or within a dial, e.g., a dial associated with the shoe. For example, the dial may comprise a speed lacing device. Specifically, by arranging the at least one sensor, such as the goniometer, at and/or within the dial, the midsole of the shoe may be unaffected, e.g., may be kept unchanged. In some embodiments, the at least one sensor and/or the means for automatically adjusting may comprise means for processing the obtained data, e.g., the detected and/or measured slope and/or inclination. In addition, the shoe may comprise an energy storage, e.g., a battery. For example, the energy storage may be configured to provide energy (e.g., power to) the means for processing and/or the at least one sensor and/or the means for automatically adjusting.
[0116] In some embodiments, the means for automatically adjusting may be configured to adjust the rocker point based on the detected and/or measured slope and/or inclination. Specifically, adjusting the rocker point based on the detected and/or measured slope and/or inclination may comprise classifying the detected and/or measured slope and/or inclination. For example, the detected and/or measured slope and/or inclination may be classified as uphill, downhill, or level. In particular, classifying the detected and/or measured slope and/or inclination as uphill, downhill, or level may comprise determining that the detected and/or measured slope and/or inclination is above or below a threshold. In some embodiments, the detected and/or measured slope and/or inclination may be above or below a threshold for, e.g., 5 consecutive steps (but any number of steps may be suitable). For example, when the detected and/or measured slope and/or inclination S is above a first threshold t_1, e.g., St_1, the detected and/or measured slope and/or inclination may be classified as uphill. For example, the first threshold t_1 may be in the range from 0.5% to 7% grade, in the range from 1% to 6% grade, in the range from 1.5% to 5% grade, in the range from 2% to 4% grade, or in the range from 2.5% to 3.5% grade. In addition, or alternatively, when the detected and/or measured slope and/or inclination S is below a second threshold t_2, e.g., St_2, the detected and/or measured slope and/or inclination may be classified as downhill. For example, the first threshold t_1 may be in the range from 7% to 0.5% grade, in the range from 6% to 1% grade, in the range from 5% to 1.5% grade, in the range from 4% to 2% grade, or in the range from 3.5% to 2.5% grade. In general, the means for automatically adjusting may be adapted to adjust the rocker point at least partially based on the classification described above.
[0117] In some embodiments, the at least one sensor may be adapted so as to detect and/or to measure a ground contact time. For example, detecting and/or measuring the ground contact time may be based on a detected and/or measured acceleration, e.g., the at least one sensor may comprise an accelerometer. For example, based on the detected and/or measured acceleration, a landing and/or take off associated with a step may be determined. In some embodiments, the means for automatically adjusting may be adapted so as to adjust the rocker point based on the detected and/or measured ground contact time. For example, the rocker point may be adjusted so as to increase a rolling. Specifically, increasing the rolling may reduce a fatigue of the athlete. In particular, with fatigue during long runs, the ground contact time may increase. Therefore, adjusting the rocker point based on the ground contact time allows for taking into account the fatigue of the athlete, thereby improving the performance of the athlete. Generally, the at least one sensor may be arranged at a dial and/or at a midsole. In addition, or alternatively, the at least one sensor may be embedded within the dial and/or within the midsole. In some embodiments, the at least one sensor, e.g., the accelerometer, may be combined with the goniometer into a unit.
[0118] In some embodiments, the at least one sensor may be adapted so as to detect and/or to measure impact accelerations, e.g., impact accelerations during an initial ground contact. For example, detecting and/or measuring the impact accelerations may be based on a detected and/or measured acceleration, e.g., the at least one sensor may comprise an accelerometer. In addition, the impact accelerations may be based on a striking of the foot or shoe of the athlete. Generally, the means for automatically adjusting may be adapted so as to adjust the rocker point based on the detected and/or measured impact accelerations. Specifically, the means for automatically adjusting may be configured to adjust the rocker point when a striking of the foot or shoe of the athlete changes. For example, when the striking shifts from a heel-striking to a midfoot-striking and/or a forefoot-striking, the means for automatically adjusting may adjust the rocker point such that the rocker point is shifted more forwards, e.g., towards a region adapted to receive a forefoot.
[0119] In some embodiments, the at least one sensor, e.g., the accelerometer and/or the goniometer and/or piezo-electric devices (e.g., for detecting and/or measuring a pressure) may be arranged at and/or in the shoe together. Alternatively, different sensors may be arranged at different locations. In some embodiments, the at least one sensor may be arranged at a heel portion of the shoe. For example, the at least one sensor may be arranged at and/or within dial of the shoe, e.g., a dial arranged at a rearmost portion of the shoe. For example, the at least one sensor may be attached to a heel counter.
[0120] In addition, or alternatively, the at least one sensor may be arranged at a region of the shoe adapted to face and/or contact a dorsal side of a foot. For example, the region may be adapted to face and/or contact a dorsum of a foot. Specifically, the at least one sensor may be arranged at laces of the shoe.
[0121] In addition, or alternatively, the at least one sensor may be arranged at and/or within the midsole of the shoe. In addition, or alternatively, the at least one sensor may be embedded inside the shoe. For example, the at least one sensor may be arranged below an insole of the shoe.
[0122] In some embodiments, automatically adjusting the rocker point of the shoe may comprise means for determining a rocker point of the shoe. For example, the means for determining a rocker point of the shoe may comprise a processor and/or a storage medium. For example, determining the rocker point of the shoe may be at least partially based on an algorithm. Specifically, the algorithm for determining the rocker point of the shoe may be at least partially based on data from the at least one sensor. More specifically, the algorithm for determining the rocker point may comprise comparing the data from the at least one sensor to one or more thresholds. As described above, in some embodiments the threshold may be based on a grade of a surface to indicate whether the athlete is traveling uphill or downhill, and the rocker point may be adjusted based on the grade. In some embodiments, the threshold may be based on a speed of the athlete (for example, the rocker point may be adjusted based on the speed of the athlete relative to the threshold). In some embodiments, the threshold may be based on the flight phase of the athlete (for example, the rocker point may be adjusted based on the flight phase of the athlete relative to the threshold). In some embodiments, the threshold may be based on ground contact time (for example, the rocker point may be adjusted based on the ground contact time of the athlete relative to the threshold). In some embodiments, the threshold may be based on the impact acceleration of the athlete (for example, the rocker point may be adjusted based on the impact acceleration of the athlete relative to the threshold).
[0123]
[0124] In some embodiments, the plate 120 may be an internal reinforcement element and may fully extend through the segment 110 and the neighboring segment 130b. Further, the plate 120 may extend at least partially through the neighboring segment 130a and the neighboring segment 130c. For example, the plate 120 may be coupled to the neighboring segment 130a and the neighboring segment 130c such that there is little to no relative movement between the plate 120 and the neighboring segments 130a, 130c. In some embodiments, the segment 110 and the neighboring segment 130b may comprise channels that extend through the segment 110 the neighboring segment 130b and are configured to receive the plate 120. The segment 110 and the neighboring segment 130b may then move along the plate 120 to move along the path 160.
[0125] In some embodiments, the plate 120 may follow a curvature to achieve certain beneficial mechanical properties. In some embodiments, the curvature of the plate 120 may be designed to achieve a certain local bending stiffness. For example, the closer the plate 120 is to a ground surface the stiffer the plate 120 may be. In some embodiments, the plate 120 may comprise a curvature which follows a curvature of the upper 101 and/or a curvature of the sole 102. In addition, or alternatively, the curvature of the plate 120 may follow a curvature of a foot of a wearer. The plate 120 may be a stiff plate and may be stiffer than the segment 110. Generally, the rocker point adjustment element 100 may comprise multiple segments and/or multiple gaps. For example, the rocker point adjustment element may comprise at least one, at least two, or at least three segments and/or gaps. The number of segments and the number of gaps may be related. For example, there may be a correspondence between the number of segments and the number of gaps. In some embodiments, a first set of segments and/or gaps may be arranged on a portion of the shoe 10 adapted to receive a rearfoot and/or a second set of segments and/or gaps may be arranged in a portion of the shoe 10 adapted to receive a forefoot.
[0126] In some embodiments, the plate 120 may be configured such that the segment 110 is movable along the path 160. In particular, the plate 120 may extend through the segment 110 such as to enable a movement of the segment 110 with respect to the plate 120. The path 160 may be determined by the geometry and/or curvature of the plate 120 such that the segment 110 may follow the geometry and/or curvature of the plate 120 as the segment 110 moves along the path 160. In addition, the movement of the plate 120 may be confined by the neighboring segment 130a and neighboring segment 130b. In some embodiments, the segment 110 may be movable along the path 160 over the gaps 140a and/or 140b until the segment 110 reaches the neighboring segment 130a and/or the neighboring segment 130b. In some embodiments, the segment 110 may be partially movable over the gaps 140a, 140b such that the segment 110 may not reach the neighboring segments 130a, 130b as the segment 110 moves along the path 160.
[0127] In some embodiments, he segment 110 may be movable by an amount of approximately 10 mm (for example, 10 mm+/10%) in a backward direction (for example, toward the rearfoot portion of the shoe 10) and a forward direction (for example, toward the forefoot portion of the shoe 10) with respect to the plate 120. In some embodiments, the distance the segment 110 may move may differ for the forward direction and the backward direction. For example, the movement in the forward direction may be larger than the movement in the backward direction, and vice versa. In some embodiments, moving the segment 110 may move a respective rocker point of the shoe. Such embodiments are further described below.
[0128] In some embodiments, the segment 110 may comprise foam. In addition, or alternatively, the segment 110 may comprise non-foam materials. For example, the segment 110 may comprise block foam and/or particle foam. Similarly, the neighboring segments 130a, 130b, 130c may comprise foam. In some embodiments, the segment 110 and the neighboring segments 130a, 130b, 130c may comprise the same material. In some embodiments, the material of the neighboring segments 130a, 130b, 130c may differ from the material of the segment 110.
[0129] In some embodiments, the segment 110 may have the shape of a block and may extend from a medial side of the shoe 10 to a lateral side of the shoe 10. Similarly, the neighboring segment 130b may have the shape of a block and may extend from the medial side of the shoe 10 to the lateral side of the shoe 10. The neighboring segments 130a and 130c may extend from the medial side of the shoe 10 to the lateral side of the shoe 10 and their respective geometries may follow the geometry of the shoe 10, i.e., the neighboring segment 130a may have a front part which is rounded off and the neighboring segment 130c may have a rear part which is rounded off. In some embodiments, the edges of the segment 110 may be rounded off and also the edges of the neighboring segments 130a, 130b, 130c may be rounded off. In some embodiments, the edges of the segment 110 and/or the edges of the neighboring segments 130a, 130b, 130c may comprise bevels. For example, the segment 110 and/or the neighboring segments 130a, 130b, 130c may comprise beveled edges to offer a smoother transition from the segment into the respective gap and vice versa when the shoe 10 is in use.
[0130] In some embodiments, the segment 110 may be arranged in a portion of the shoe 10 which is adapted to receive a forefoot. For example, independent of the position of the segment 110 relative to the plate 120, the segment 110 may be located in a region adapted to receive the forefoot. In some embodiments, arranging the segment 110 in a portion of the shoe 10 which is adapted to receive a forefoot may allow adjustment of a forefoot rocker point of the shoe 10.
[0131] In some embodiments, the segment 110 may be arranged in a portion of the shoe 10 which is adapted to receive a rearfoot. Arranging the segment in a portion of the shoe 10 which is adapted to receive a rearfoot may allow adjustment of a rearfoot rocker point of the shoe.
[0132] In some embodiments, the rocker point adjustment element 100 may comprise segments in a portion of the shoe 10 adapted to receive a forefoot and in a portion of the shoe 10 adapted to receive a rearfoot. For example, the segments in the forefoot portion and the segments in the rearfoot portion may be independently adjustable. Thereby, the rearfoot rocker point and the forefoot rocker point of the shoe may be adjusted independently of each other.

[0134] In some embodiments, the rods 220a, 220b, 220c, 220d, 220e may be configured to guide the segment 210 along the path 260 such that the segment 210 is movable along the path 260. For example, the segment 210 may comprise channels that extend through the segment 210 and are configured to receive a respective one of the five rods. The segment 210 may then move along the rods 220a, 220b, 220c, 220d, 220e to move along the path 260. In some embodiments, moving the segment 210 along the path 260 may move a respective rocker point of the shoe along the path 260. In embodiments where the rods 220a, 220b, 220c, 220d, 220e may be essentially straight (for example, within ten percent of being straight), the segment 210 can be moved along the path 260 in an essentially linear motion.
[0135] In some embodiments, the movement of the segment 210 may be confined by the neighboring segments 230a and 230b. For example, the segment 210 may be movable over the gaps 240a, 240b (for example, along the path 260) until the segment 210 reaches the neighboring segments 230a, 230b. The distance between the neighboring segment 230a and the neighboring segment 230b may be larger than a size and/or width of the segment 210 (for example, to allow movement of the segment 210). In particular, the size of the gaps 240a, 240b may be based on a difference between the distance between the neighboring segment 230a and the neighboring segment 230b and the size and/or width of the segment 210.
[0136] With respect to the rocker point adjustment element 200, a transverse projection of the segment 210 and the neighboring segments 230a, 230b along a longitudinal axis of the shoe may not comprise an essentially continuous segment. In fact, in some embodiments, the transverse projection would comprise gaps, namely the gaps 240a and 240b. More precisely, the transverse projection would comprise gaps which may have the same size and/or width and/or geometry as the gaps 240a, 240b. In some embodiments, the segment 210 may comprise the shape of a block and may extend from the medial side of the shoe 20 to the lateral side of the shoe 20. The segment 210 may comprise foam, for example block foam and/or particle foam. Similarly, the neighboring segments 230a, 230b may comprise foam. In some embodiments, the material of the segment 210 may be the same material as the material of the neighboring segments 230a, 230b. In some embodiments, the material of the segment 210 may be different that the material of the neighboring segments 230a, 230b.
[0137] In some embodiments, the rods 220a, 220b, 220c, 220d, 220c may be internal reinforcement elements. For example, the rods 220a, 220b, 220c, 220d, 220e may extend through the segment 210 (for example, through channel that extend through the segment 210). In particular, the rods 220a, 220b, 220c, 220d, 220e may extend through the segment 210 in such a way as to enable the movement of the segment 210 along the path 260. In some embodiments, the rods 220a, 220b, 220c, 220d, 220e may further extend through the neighboring segments 230a and 230b. Generally, the segments (for example, the segment 110, the segment 210, etc.) may be movably coupled to the reinforcement elements, e.g., the rods 220a, 220b, 220c, 220d, 220e and/or the plate 120 of
[0138] In some embodiments, the rocker point adjustment element 200 may comprise two screws 250a, 250b for fixing the segment 210 in a respective first position. In particular, the screws 250a, 250b may extend at least partially through the segment 210. In some embodiments, the screw 250a may couple the segment 210 to the rod 220b and the screw 250b may couple the segment 210 to the rod 220d. In some embodiments a different number of screws may be used, and the different screws may couple the segment 210 to different rods. The fixing mechanism is described in more detail with reference to
[0139]
[0140] In some embodiments, the segment 310 may comprise protrusions 315a, 315b, which may be located at opposite sides of the segment 310. Further, the neighboring segment 320a may comprise a recess 325a which may be adapted to receive at least a part of the protrusion 315a. Further, the neighboring segment 320b may comprise a recess 325b which may be adapted to receive at least a part of the protrusion 315b. For example, the protrusions 315a, 315b and the recesses 325a, 325b may be configured such that independently of the position of the segment 310 on the path 340, at least a part of the protrusion 315a extends into the recess 325a and/or at least a part of the protrusion 315b extends into the recess 325b.
[0141] In some embodiments, a transverse projection of the segment 310 and the neighboring segments 320a, 320b with respect to a longitudinal axis 362 of the shoe 30 may comprise an essentially continuous segment. In particular, the transverse projection may not fully comprise gaps 330a, 330b as the gaps 330a, 330b may not extend linearly from the medial side of the shoe 30 to the lateral side of the shoe 30. More precisely, the gaps 330a, 330b may extend from the lateral side of the shoe 30 to the medial side of the shoe 30 via a curved path, wherein the curved path is based on the shape and/or geometry of the protrusions 315a, 315b and/or the recesses 325a, 325b.
[0142] In some embodiments, the protrusions 315a, 315b may have a different geometry and/or a different size. In some embodiments, the overlapping geometry may only be implemented with respect to one side of the segment 310. For example, the segment 310 may comprise one of the protrusions 315a or 315b and the corresponding neighboring segment 320a or 320b may comprise the corresponding recess 325a or 325b. In an example embodiment, the neighboring segment 320a may comprise the recess 325a and the segment 310 may comprise the protrusion 315a. Furthermore, the protrusion 315b may not be present and the segment 310 may have a flat side towards the neighboring segment 320b. Similarly, the neighboring segment 320b may not comprise the recess 325b and may have a flat side towards the segment 310. Similarly, in some embodiments the neighboring segment 320a may have a flat side toward the segment 310, and the segment 310 may have a flat side toward the neighboring segment 320a (such that the neighboring segment 320a may not comprise the recess 325a).
[0143]
[0144]
[0145] In some embodiments, the rocker point adjustment element 400 may comprises screws 450a, 450b. In some embodiments, the rocker point adjustment element 400 may comprise only one screw or at least three screws. The screws 450a, 450b may be configured to fix the segment 410 at a respective first position. For example, the segment 410 may comprise screw threads 460a, 460b which are configured to receive the respective screws 450a, 450b. In particular, the screw threads 460a, 460b may extend from a medial side and/or a lateral side of the segment 410 towards a center of the shoe 40 and/or the segment 410. In general, the number of screws and/or screw threads may be different. For example, the number of screw threads on a first side of the segment 410 may be different from the number of screw threads on a second side of the segment 410.
[0146] In some embodiments, when the screws 450a, 450b are screwed into the respective screw thread 460a, 460b the screws and the screw thread are configured to fix the segment 410 at a respective first position relative to the neighboring segments 430a, 430b. For example, the segment 410 may be fixed at a first position such that the gaps 440a, 440b are produced. In some embodiments, the segment 410 may be fixed at a first position such that a rocker point of the shoe is fixed at a respective first position. The first position of the rocker point may correspond to an optimal rocker point of the shoe with respect to an individual athlete.
[0147]
[0148] In an example embodiment, when the screw 530 is screwed into the screw thread 540, the screw 530 may contact the means for guiding 520. By contacting the means for guiding 520, the screw 530 may fix the segment 510 at a respective first position. For example, contacting the means for guiding 520 by the screw 530 may establish a friction between the screw 530 and the means for guiding 520 such that the segment 510 may be fixed at the respective first position. Generally, the screw 530 may be configured such that the head of the screw forms an essentially flat surface with the segment 510, when the screw 530 contacts the means for guiding 520.
[0149] In general, the rocker point adjustment element may be configured such that the screw 530 can be loosened, after the screw 530 has fixed the segment 510 at the respective first position. Loosening the screw 530 may unfasten the segment 510 such that the segment 510 can be moved to a respective second position. Moving the segment 510 to the respective second position may move a respective rocker point of the shoe to a respective second position.
[0150] Generally, the means for fixing 500 illustrated with respect to
[0151]
[0152]
[0153] In some embodiments, the rocker point adjustment element 600 may comprise a pin-hole system, wherein the pin-hole system may comprise at least two pins 650a, 650b and a plurality of holes. For example, a pin 650a may be arranged on a lateral side of the shoe and a pin 650b may be arranged on a medial side of the shoe. In general, the holes may be part of the segment 610. For example, the segment 610 may comprise six holes 660a, 660b, 660c, 665a, 665b and 665c. In particular, the holes 660a, 660b, 660c may be arranged on a lateral side of the shoe and the holes 665a, 665b, 665c may be arranged on a medial side of the shoe. In general, the number of holes arranged on the lateral side of the shoe and the number of holes arranged on the medial side of the shoe may coincide. In some embodiments the number of holes may be different. Generally, there may be two or more pins in different parts of the means for guiding (for example, the rods 620a, 620b, 620c, 620d, 620c) to fix the segment 610 and/or rocker points at a location along the path 662. For example, the number of holes arranged on the lateral side and/or medial side may be two. Alternatively, the number of holes arranged on the lateral side and/or medial side may be larger than three.
[0154] In some embodiments, the at least two pins 650a, 650b may generally be part of the means for guiding, for example the segment 610 and/or the rods 620a, 620b, 620c, 620d, 620c. For example, the pin 650a on the lateral side of the shoe may be associated with the rod 620a and the pin 650b on the medial side of the shoe may be associated with the rod 620e. In general, the holes 660a, 660b, 660c, 665a, 665b and 665c and the pins 650a, 650b may be configured such that the pins 650a, 650b can extend through the respective holes 660a, 660b, 660c, 665a, 665b and 665c. When the pins 650a, 650b extend through one of the respective holes, for example when pin 650 a extends through hole 660b and pin 650b extends though hole 665b, the pins 650a, 650b may fix the segment 610 at a respective first position. In particular, fixing the first segment at a respective first position by means of the pins 650a, 650b and the holes 660a, 660b, 660c, 665a, 665b and 665c may fix a respective rocker point of the shoe 60 at a respective first position.
[0155] In some embodiments, the pins 650a, 650b may be configured such that they are movable with respect to an elongation direction of the respective hole. For example, the pins 650a, 650b may be movable towards a center of the shoe. In particular, the pins 650a, 650b may be pushed towards the center of the shoe. Pushing the pins 650a, 650b towards the center of the shoe may unfasten the segment 610 such that the segment 610 becomes movable with respect to the path. In general, the segment 610 may be moved from the first position to a second position and may be fastened at the second position when the pins 650a, 650b pop up into the holes corresponding to the second position, e.g., the holes 660a or 660c, thereby moving the respective rocker point of the shoe from the first rocker point position to a respective second rocker point position.

[0159] As illustrated with respect to
[0160] In some embodiments, the rocker point adjustment element 700 may comprise at least one screw 750 to fix the segment 710 at a respective first position.
[0161] In some embodiments, the rocker point adjustment element 700 may comprise at least one fixing element, such as the fixing element 760a and/or 760b. In some embodiments, the at least one fixing element 760a, 760b may be configured to be inserted between the segment 710 and at least one neighboring segment 730a, 730b. For example, the fixing element 760a may be configured to be inserted between the neighboring segment 730a and the segment 710 and/or the fixing element 760b may be configured to be inserted between the neighboring segment 730b and the segment 710.
[0162] Generally, different configurations of the fixing element 760a and/or 760b, e.g., a size, and/or the different positions of the fixing element 760a and/or 760b within the shoe 70 may result in different rocker points of the shoe. For example, the arrangement of the fixing element 760a illustrated in
[0163] As shown in
[0164] In some embodiments, the size and/or the shape and/or the number of fixing elements 760a, 760b may be such as to fix the segment 710 at a respective first position. For example, if the first position of the segment 710 is such that the gap 740a is produced, the size and/or the shape and/or the number of the fixing elements 760a, 760b may correspond to the size of the gap 740a. As another example, if the first position of the segment 710 is such that the gap 740a and 740b is produced, two fixing elements 760a and 760b may be used, wherein the size and/or shape of the fixing element 760a may correspond to the size and/or shape of the gap 740a and/or the size and/or shape of the fixing element 760b may correspond to the size and/or shape of the gap 740b.

[0166]
[0167]
[0168] In some embodiments, moving the segment 810a from the first configuration to the second configuration may move a rocker point of the shoe 80. In particular, moving the segment 810a from the first configuration to the second configuration may move the rearfoot rocker point 870 of the shoe 80 from a first position to a second position. For example, by moving the segment 810a towards the rear end of the shoe 80 the rearfoot rocker point 870 may be moved towards the rear end of the shoe. In addition, or alternatively, moving the segment 810a may also influence the forefoot rocker point 872 of the shoe. For example, moving the segment 810a may at least partially move the forefoot rocker point 872 of the shoe 80.
[0169]
[0170]
[0171] In some embodiments, the segment 910a and the segment 910b may be movable independently of each other, e.g., a position of the segment 910a may be changed independently of a position of the segment 910b. In some embodiments, the rocker point adjustment element 900 may comprises neighboring segments 930a, 930b, which may be separated from the segments 910a, 910b by gaps 940. In particular, the configuration of the gaps 940 may be based on the position of the segments 910a, 910b. For example, the segment 910a may be positioned so as to be separated from the neighboring segment 930a by the gap 940 and to be separated from the neighboring segment 930b by the gap 940. Similarly, the segment 910b may be positioned such as to be separated from the neighboring segment 930b by the gap 940 but to be in contact with the neighboring segment 930a.
[0172] In some embodiments, the rocker point adjustment element 900 may comprise four rods 920a, 920b, 920c, 920d. In particular, a first group of rods 920a, 920b may extend through the segment 910a. The first group of rods 920a, 920b may at least partially define a path 970 for the segment 910a. For example, the segment 910a may be moved along the path 970 at least partially defined by the first group of rods 920a, 920b. Furthermore, a second group of rods 920c, 920d may extend through the segment 910b. The second group of rods 920c, 920d may at least partially define a path 972 for the segment 910b. For example, the segment 910b may be moved along the path 972 at least partially defined by the second group of rods 920c, 920d. In some embodiments, the path 970 defined by the first group of rods 920a, 920b may be essentially parallel (for example, within ten degrees of being parallel) to the path 972 defined by the second group of rods 920c, 920d. In some embodiments, the two paths may not be parallel, but may comprise different orientations and/or different directions.
[0173] In some embodiments, the rocker point adjustment element may comprise at least three, or at least four mutually transversely spaced apart segments. For example, each of the rods 920a, 920b, 920c, 920d may guide a segment that is transversely separated from the other rods 920a, 920b, 920c, 920d. For example, the rod 920a may extend through a first segment and guide the first segment along a first path. In addition, or alternatively, the rod 920b may extend through a second segment and guide the second segment along a second path. In addition, or alternatively, the rod 920c may extend through a third segment and guide the third segment along a third path. In addition, or alternatively, the rod 920d may extend through a fourth segment and guide the fourth segment along a fourth path. Specifically, there may be a correspondence between the number of rods of the rocker point adjustment element and the number of mutually transversely spaced apart segments.
[0174] In addition, or alternatively, the rods 920a, 920b, 920c, 920d may define groups of rods. A group of rods may comprise at least two of the rods 920a, 920b, 920c, 920d. In some embodiments, a group of rods may be associated with a segment 910a, 910b. Being associated with a segment may mean that the rods in the group extend through the corresponding segment. In addition, or alternatively, being associated with a segment may mean that the rods in the group guide the segment along a path (for example, the path 970 or the path 972).
[0175] In some embodiments, the arrangement of the segments 910a, 910b according to
[0176] In some embodiments, the rocker point adjustment element 900 comprising longitudinally and transversely spaced apart segments 910a, 910b (spaced apart, for example, via the gap 940 and the gap 950) may allow for a micro-adjustment of the rocker point of the shoe. In particular, the rocker point adjustment element 900 comprising longitudinally and transversely spaced apart segments 910a, 910b associated with a lateral and a medial side respectively may allow for a micro-adjustment of the rocker point of the shoe. Allowing for a micro-adjustment of the rocker point of the shoe may enhance the adaption of the rocker point to the individual needs of the athlete.
[0177]
[0178] In some embodiments, the rod 1020a may guide the segment 1010 along a first sub-path 1070 and the rod 1020b may guide the segment 1010 along a second sub-path 1072. In some embodiments, the first sub-path 1070 and the second sub-path 1072 may be parallel paths. In addition, or alternatively, the first and the second sub-paths 1070, 1072 may comprise different directions, e.g., the direction of the first sub-path 1070 and the direction of the second sub-path 1072 may form an angle and/or an orientation of the first sub-path 1070 may be opposite to an orientation of the second sub-path 1072.
[0179] In some embodiments, the rocker point adjustment element 1000 may be configured such that the segment 1010 can be moved along at least two paths. For example, the first path may comprise a configuration in which the first sub-path 1070 defined by the rod 1020a is parallel to the second sub-path 1072 defined by the rod 1020b. In particular, moving the segment 1010 along the first path may move the segment 1010 in a longitudinal direction 1080 of the shoe and/or rocker point adjustment element 1000.
[0180] In addition, or alternatively, a second path may comprise a configuration in which the orientation of the first sub-path 1070 defined by the rod 1020a may be opposite to an orientation of the second sub-path 1072 defined by the rod 1020b. For example, moving the segment 1010 along the second path may comprise moving a first portion of the segment 1010 along the first sub-path 1070 defined by the rod 1020a and a second portion of the segment 1010 along the second sub-path 1072 defined by the rod 1020b. In particular, moving the first portion of the segment 1010 along the first sub-path 1070 may comprise moving the first portion of the segment 1010 by a first amount in a first direction/orientation. In addition, or alternatively, moving the second portion of the segment 1010 along the second sub-path 1072 may comprise moving the second portion of the segment 1010 by a second amount in a second direction/orientation. For example, the first direction/orientation may be opposite to the second direction/orientation. More specifically, the first direction/orientation may point towards a rear end of the shoe and/or rocker point adjustment element 1000 and the second direction/orientation may point towards a front end of the shoe and/or rocker point adjustment element 1000.
[0181] Moving the segment 1010 according to the second path may induce a torsion of the segment 1010 with respect to the shoe and/or rocker point adjustment element 1000. In some embodiments, inducing a torsion of the segment 1010 may adjust a geometry and/or size of gaps 1040a, 1040b. In addition, or alternatively, inducing a torsion of the segment 1010 may adjust the rocker point of the shoe. In particular, inducing a torsion of the segment 1010 may adjust a forefoot rocker point and/or a rearfoot rocker point of the shoe.
[0182] As illustrated in
[0183]
[0184] In addition, or alternatively, the segment 1010 may be separated from the neighboring segment 1030b by a gap 1040b, wherein the geometry and/or size of the gap 1040b with respect to the second configuration may differ from the geometry and/or size of the gap 1040b with respect to the first configuration. In particular, a distance between the segment 1010 and the neighboring segment 1030b may vary with respect to a transverse direction. For example, the segment 1010 may contact the neighboring segment 1030b at a medial side of the shoe and the separation and/or the size of the gap and/or the distance may increase towards a lateral side of the shoe. In other words, a boundary of the segment 1010 and a boundary of the neighboring segment 1030b may not be parallel, e.g., they may intersect at a certain angle.
