An article of footwear includes a strobel having an interior surface and an exterior surface formed on an opposite side from the interior surface, the strobel defining a footbed and a peripheral wall extending transversely from the footbed to a terminal edge. The article of footwear additionally includes an upper attached to the terminal edge of the strobel along a peripheral seam to define an interior void for receiving a foot, the peripheral seam configured to extend along a side of the interior void.

A sole structure for an article of footwear includes an upper layer formed of a first foam material and a lower layer formed of a second foam material and having a hardness that is greater than a hardness of the upper layer. In addition, a plate can be disposed between the upper layer and the lower layer, where the plate has a hardness that is greater than each of the upper and lower layers.

A sole structure includes a foam element extending from a forefoot region to a heel region. A bottom surface of the foam element includes a recess formed in the forefoot region. The sole structure also includes a cushioning arrangement disposed in the recess of the foam element. The cushioning arrangement has a proximal end adjacent to the bottom surface of the foam element and a distal end formed on an opposite side of the cushioning arrangement than the proximal end, the cushioning arrangement including at least one medial bladder proximate to a medial side of the sole structure and at least one lateral bladder proximate to a lateral side of the sole structure. An outsole includes an anterior outsole and a posterior outsole attached to the bottom surface of the foam element and the distal end of the cushioning arrangement. The anterior outsole is spaced apart from the posterior outsole.

A pre-tensioned article and method of making an article of footwear involving pre-tensioning a sole structure during manufacturing. In some embodiments, the sole structure may include a plurality of apertures that provide an auxetic effect. In further embodiments, the upper may also be pre-tensioned in a similar manner as the sole structure.

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 sole structure for an article of footwear includes a heel region, a forefoot region, and a midfoot region disposed between the heel region and the forefoot region. The sole structure also includes a fluid-filled chamber including a first barrier layer cooperating with a second barrier layer to define a first segment extending along a medial side of the sole structure within the heel region, a second segment extending from the medial side in the forefoot region to a lateral side in the heel region and along a lateral side of the sole structure within the heel region, and a web area disposed between and connecting the first segment and the second segment. The first barrier layer being attached to the second barrier layer within the web area.

A sole structure for an article of footwear includes a foam element having a top surface and a bottom surface. The foam element includes a recess (i) formed in one of the top surface or the bottom surface, (ii) extending from a first end in a forefoot region of the sole structure to a second end in a mid-foot region of the sole structure, (iii) having a first edge extending between the first end and the second end and disposed proximate to a peripheral region of the sole structure, and (iv) a second edge extending between the first end and the second end and disposed at an interior region of the sole structure. A cushioning arrangement is disposed within the recess and includes an outer surface that is substantially flush with the one of the top surface or the bottom surface of the foam element.

A sole structure includes a foam element extending from a forefoot region to a heel region. A lower surface of the foam element includes a recess formed in the forefoot region. The sole structure also includes a posterior cushioning arrangement extending along a peripheral region of the sole structure from a heel region to a mid-foot region, and an anterior cushioning arrangement disposed in the recess of the foam element. The anterior cushioning arrangement has a proximal end adjacent to the lower surface of the foam element and a distal end formed on an opposite side of the anterior cushioning arrangement than the proximal end. The anterior cushioning arrangement includes at least one medial bladder proximate to a medial side of the sole structure and at least one lateral bladder proximate to a lateral side of the sole structure.

A sole structure for an article of footwear having an upper includes a midsole. The midsole may include a cushion and a chassis. The cushion extends from a forefoot region to a heel region of the sole structure. The chassis is disposed between a top side of the cushion and the upper. An outsole is mounted to a bottom surface of the midsole. The outsole includes a first outsole portion, a second outsole portion and a third outsole portion. The first outsole portion, the second outsole portion and the third outsole portion are spaced apart from each other so as to provide flexibility to the sole structure. The first outsole portion, the second outsole portion and the third outsole portion may be formed of a first material and a second material. The second material is more durable relative to the first material.

A sole structure for an article of footwear having an upper includes a cushion member and a chassis. The cushion member extends from a forefoot region to a heel region of the sole structure. The cushion member includes a first series of lobes alternating with a first series of recesses along a length of the cushion member. The first series of lobes and the first series of recesses extend along one of a medial side of the sole structure and a lateral side of the sole structure. The chassis is disposed between the cushion member and the upper and includes a series of first supports alternating with a second series of recesses. The supports of the series of first supports are aligned and in contact with respective lobes of the first series of lobes and the second series of recesses are aligned with the first series of recesses.
