An article of footwear is provided having an elevated plate structure incorporated in the sole structure and optionally including a fluid-filled chamber. The elevated plate structure can include an upper plate and a plurality of legs extending downward toward the outsole. End portions of the legs can engage an upper region of the outsole. The elevated plate structure can form a cage region that can optionally include a fluid-filled chamber substantially disposed therein. The elevated plate structure can further include a lower plate disposed at an upper region of the outsole, which can form a lower portion of the cage region. Portions of the legs can be integrated with impact-attenuating members in the heel region in various configurations and can provide features for the impact-attenuating members, such as support, impact-attenuation and adjustable impact-attenuation features.

A method of forming a plate for an article of footwear is disclosed. The method includes applying a first strand portion to a base layer including positioning adjacent segments of the first strand portion to form a first layer on the base layer. The adjacent segments of the first strand portion having a greater density across a width of the plate between a medial side and a lateral side at a forefoot region of the plate than at a midfoot region of the plate and at a heel region of the plate. The method also includes applying at least one of heat and pressure to the first strand portion and to the base layer to conform the first strand portion and the base layer to a predetermined shape.

A running shoe comprises an upper and a midsole attached to the upper, the midsole having a front portion corresponding to a forefoot and a rear portion corresponding to a heel. The front portion of the midsole may define a toe spring of at least 40 mm and a plurality of flex grooves, the plurality of flex grooves including one or more horizontal flex grooves and one or more longitudinal flex grooves, the horizontal flex groove(s) extending in a lateral to medial direction of the running shoe and allowing the front portion of the midsole to lie flat in response to application of less than 15 pounds of force against the toe spring, the longitudinal flex groove(s) extending in a front to back direction of the running shoe. The rear portion of the midsole may have a flat bottom that is narrower than the upper.

Aspects relate to a portable device that may be used to identify a critical intensity and an anaerobic work capacity of an individual. The device may utilize muscle oxygen sensor data, speed data, or power data. The device may utilize data from multiple exercise sessions, or may utilize data from a single exercise session. The device may additionally estimate a critical intensity from a previous race time input from a user.

To provide footwear, in which a cushion layer is effectively bent even though an outsole of footwear has a thick cushion layer to distribute weight, thereby putting no stain on movement during walking, the footwear according to the disclosure includes uppers provided to surround at least a certain region of a wearer's foot; a supporter disposed below the uppers and supporting the foot; and a walking assister provided in the supporter, adjacent to a metatarsophalangeal joint area of the foot, and generating elasticity in a walking direction of the wearer.

A shock absorber includes a shock absorbing portion having a three-dimensional shape formed by a wall in which an outer shape is defined by a pair of parallel curved surfaces. The shock absorbing portion includes at least one three-dimensional structure body obtained by changing a shape of a unit structure body thickened based on a unit structure of a Schwartz P structure. The shape of the three-dimensional structure body in an unloaded state is a shape obtained by changing the shape of the unit structure so as to follow the shape change of the unit structure body, which is the regular hexahedron shaped space occupied by the unit structure body, into the trapezoidal space.

A shoe sole includes a sole body including a midsole and a shock absorber. The shock absorber is disposed adjacent to the midsole in a direction intersecting a thickness direction of the sole body. The midsole includes a first opposing surface that is opposed to the shock absorber and inclined with respect to the thickness direction, and the shock absorber includes a shock absorbing portion having a three-dimensional shape formed by a wall in which an outer shape is defined by a pair of parallel curved surfaces and a plate-shaped fixing wall including a second opposing surface opposed to the first opposing surface. The fixing wall is inclined with respect to the thickness direction such that the second opposing surface is parallel to the first opposing surface. The shock absorber is fixed to the midsole by bonding the first opposing surface and the second opposing surface through an adhesive layer.

Disclosed is an insole or footbed for footwear that optimizes the comfort and performance of the footbed via a modified construction to the shoe's upper and midsole to accommodate a preferred footbed construction.

Ground-engaging components for articles of footwear include: (a) an outer perimeter boundary rim that at least partially defines an outer perimeter of the ground-engaging component, wherein the outer perimeter boundary rim defines an upper-facing surface and a ground-facing surface opposite the upper-facing surface, wherein the outer perimeter boundary rim defines an open space at least at a forefoot support area of the ground-engaging component; and (b) a matrix structure extending from the outer perimeter boundary rim (e.g., the ground-facing surface and/or the upper-facing surface) and across the open space at least at the forefoot support area to define an open cellular construction with plural open cells across the open space at least at the forefoot support area, wherein a plurality (e.g., at least a majority) of the open cells have curved perimeters with no distinct corners.

A plurality of orthotic systems are provided. One bi-layer system is constructed from a single sheet of fabric that is molded into two layers. One tri-layer system includes a base layer; a mid-layer, and an upper layer. The upper layer is joined to the mid-layer and the mid-layer is joined to the base layer. The coupling of the base layer, the mid-layer and the upper layer create a rear spring section, a mid-spring section and a front spring section in which the upper layer is suspended over the mid-layer and the heel portion is suspended on the proximal heel end of the base layer.
