Disclosed herein are improved cross-linked resilin compositions and methods of making these improved compositions. These include new methods of cross-linking resilin compositions, use of polar nonaqueous solvents for adjusting material properties of cross-linked resilin solid compositions, and resilin foam compositions and methods of making the same.

A shoe sole is basically provided with a first layer and a second layer. The second layer is coupled to the first layer. The second layer has a forefoot part and a tarsal part. The forefoot part extends along the first layer and the tarsal part is configured to be displaceable relative to the first layer.

A method for forming a plate includes attaching a first strand portion to a flexible substrate to form a first layer on the substrate and positioning a second strand portion on the first layer to form a second layer on the first layer in a plurality of discrete regions on the substrate. The method also includes positioning a plurality of traction elements into corresponding cavities formed into a first mold surface and positioning the substrate on the first mold surface to change a shape of the substrate. At least one of heat and pressure is applied to the first strand portion, the second strand portion, the substrate, and the traction elements to conform the substrate to the shape of the first mold surface and form the traction elements into the substrate at each of the discrete regions. The method also includes incorporating the substrate into an article of footwear.

A sole structure for an article of footwear includes a first plate extending from a forefoot region of the sole structure to a heel region of the sole structure. The first plate has a first surface and a second surface formed on an opposite side of the first plate than the first surface. The sole structure further includes a second plate extending from the forefoot region to the heel region. The second plate has a third surface opposing the second surface of the first plate and a fourth surface disposed on an opposite side of the second plate than the third surface. The third surface is spaced apart from the second surface to define a cavity between the first plate and the second plate that extends from a medial side of the sole structure to a lateral side of the sole structure between the forefoot region and the heel region.

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 sole structure for an article of footwear is provided. The sole structure includes a midsole, a cushion disposed in the midsole and including an inner portion, and an outsole including a first surface defining a ground-contacting surface and an upper surface disposed on an opposite side of the outsole than the ground-contacting surface and opposing the cushion, the outsole including a protrusion that extends in a direction away from the midsole to a greater extent than any other portion of the outsole and being aligned with the inner portion.

A method of manufacturing a sole structure includes providing a plate within a cavity of a mold. The plate includes a base and a rib, and the base includes a first surface and a second surface. The first surface faces the upper, the second surface faces away from the first surface, and the rib projects from the second surface of the base. Moreover, the method includes providing a preform bladder member within the cavity of the mold, wherein the preform bladder member including a first member and a second member. The method additionally includes forming a bladder from the first and second members using the mold. Also, the method includes attaching the first member to the plate using the mold. Attaching the first member to the plate includes shaping the first member according to surfaces of the rib.

An article of footwear including an upper and a sole assembly secured to the upper and including a support assembly having an upper member and a lower member spaced from the upper member. A first layer is positioned beneath and in contact with the upper member and has a wave shaped profile with a plurality of first wave crests and first wave troughs. A second layer is positioned above the lower member and has a wave shaped profile with a plurality of second wave crests and second wave troughs.

Sole structures for articles of footwear, including athletic footwear, include a relatively soft and lightweight foam midsole component partially covered by at least one more rigid and/or dense cage (protective) component(s) and/or other protective component(s).

A shoe and a corresponding method for making a shoe are disclosed. A shoe according to an embodiment includes: an upper including a main body; a midsole, an outside edge of the midsole being attached to a lower edge of the main body, the midsole being formed to define a first accommodation space; and a first fill injected in the first accommodation space.
