A device for use in a shoe includes a first foot, a second foot, a third foot, a fourth foot, a first flexible leg, a second flexible leg, a third flexible leg, and a fourth flexible leg. The first flexible leg extends from the first foot and is curved. The second flexible leg extends from the second foot and is curved. The third flexible leg extends from the third foot and is curved. The fourth flexible leg extends from the fourth foot and is curved. The first flexible leg, second flexible leg, third flexible leg, and fourth flexible leg are joined together with each other at a common area. The first flexible leg, second flexible leg, third flexible leg, and fourth flexible leg are configured to store energy when a force is applied to the common area, and to return energy when the force is removed from the common area.

Devices with internal flexibility sipes, such as slits, provide improved flexibility, improved cushioning to absorb shock and/or shear forces, and improved stability of support. Siped devices can be used in any existing product that provides or utilizes cushioning and stability. These products include human and other footwear, both soles and uppers, as well as orthotics; athletic, occupational and medical equipment and apparel; padding or cushioning, such as for equipment or tool handles, as well as furniture; balls; tires; and any other structural or support elements in a mechanical, architectural, or any other product.

An article of footwear including a sole structure attached to an upper defining an internal void configured to receive a foot of a wearer is described. The sole structure includes a sole body portion having a central ridge element located in an aperture in the sole body portion and the central ridge element is configured to contact the ground and move relative to the aperture.

The present invention relates to an enhanced method for the manufacture of a plastic component (135), in particular a cushioning element for sports apparel, the method comprising: opening a mold (100) by a predetermined amount into a loading position, wherein the mold comprises at least two mold parts (110, 112) and wherein the amount by which the mold is opened influences an available loading volume of the mold, loading a material comprising expanded particles (130) into the loading volume, closing the mold into a closed position, wherein during closing of the mold the mold parts are moved together over different distances (140) in different areas of the mold, compressing the expanded particles by closing the mold and fusing at least the surfaces of the expanded particles to mold the plastic component.

Sole structures including a plate including a first polyolefin resin, and an edge portion comprising a second resin are disclosed herein. The edge portion is more flexible or less rigid than the plate. Articles of footwear formed from the sole structures are also provided. Methods of making the polyolefin resin compositions, plates, edge portions, sole structures, and articles of footwear are also provided. In some aspects, the first polyolefin resin composition includes an effective amount of a polymeric resin modifier.

An apparatus comprised of a first portion comprising a generally flexible fabric, and a second portion or layer comprising a gel material formed in a generally planar rectangular shape. Positioned below the second layer is a third portion or a damping layer having a series of dampers positioned thereon, where the dampers are elastomeric flexible and compressible. The three portions are laminated together.

An article of footwear includes a sole structure and an upper that is attached to the sole structure. The upper defines a cavity that is configured to receive a foot of a wearer. The upper is at least partially defined by a textile. The textile includes a first area that is substantially smooth. The first area defines a reference boundary that conforms to the cavity. The textile includes a second area. The second area includes a plurality of projection structures that project away from the reference boundary and outwardly from the cavity at varying heights. The second area includes a plurality of recess structures that recess away from the reference boundary and inwardly toward the cavity. The plurality of projection structures and the plurality of recess structures are in an alternating arrangement across the textile.

Components for articles of footwear and athletic equipment are provided including a high energy return foam having improved abrasion resistance. A variety of foams and foam components and compositions for forming the foams are provided. In some aspects, the foams and components including the foams can have exceptionally high energy return while also having improved durability and softness and an improved abrasion resistance. In particular, midsoles including the foams are provided for use in an article of footwear. Methods of making the compositions and foams are provided, as well as methods of making an article of footwear including one of the foam components. In some aspects, the foams and foam components can be made by injection molding or injection molding followed by compression molding.

A sole structure for an article of footwear includes a midsole and a stabilizing member. The stabilizing member can include a first end portion and a second end portion. The first end portion is positioned along the bottom surface of the midsole. A first sub-portion of the first end portion extends along a first side of the midsole and a second sub-portion of the first end portion extends across the bottom surface from the first side of the midsole to a second side of the midsole. The second portion extends upwardly from the first portion and onto the second side of the midsole to wrap around at least a portion of a periphery of a heel region of the midsole and onto the first side of the midsole.

A sole structure for an article of footwear includes a forefoot region disposed adjacent an anterior end, a heel region disposed adjacent a posterior end, and a mid-foot region disposed intermediate the forefoot region and the heel region. The sole structure further includes fluid-filled bladder having a first segment extending along a medial side in the heel region, a second segment extending along a lateral side in the heel region, and a web area disposed between the first segment and the second segment. Additionally, the sole structure includes an outer sole member having an upper portion extending from a first end in the forefoot region to a second end in the heel region. The second end of the outer sole member is received on a first side of the web area. The outer sole member also includes a rib extending downwardly from the upper portion and defining a cavity.
