An article of footwear has an upper, an outsole attached to the upper, and a midsole. The outsole includes a ground-engaging surface and an inner surface disposed on opposite sides. The midsole has a footbed and a bottom surface disposed on opposite sides. The bottom surface opposes the inner surface to define a cavity therebetween. The article of footwear also includes a first series of projections extending into the cavity from one of the inner surface and the bottom surface in a first direction toward the other of the inner surface and the bottom surface. The article of footwear also includes a second series of projection extending into the cavity from one of the inner surface and the bottom surface in the first direction toward the other of the inner surface and the bottom surface. The article of footwear also includes a quantity of particulate matter disposed within the cavity.

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 dual-layered midsole for footwear includes an internal midsole layer and an external midsole layer, which are coupled to and separated by a Strobel board. The internal midsole layer may compress and expand with the movement of a wearer of an article of footwear including the dual-layered midsole, while the external midsole may provide stability and cushion for the wearer. Materials selected for the internal and external midsole layers may provide tuned viscoelastic properties to different areas of the midsole as a function of midsole layer thickness at each sole area.

Resin compositions composed of a polyolefin copolymer, a polymeric resin modifier, and a thermoplastic vulcanizate (TPV) are provided herein. A variety of sole structures for footwear, including plates, are provided including the polyolefin-based resin compositions described herein. Articles of footwear formed therefrom are also provided. Methods of making the polyolefin-based resin compositions, plates, sole structures, and articles of footwear and sporting equipment are also provided.

A sole structure for an article of footwear can include a midsole and an outsole. The outsole can include one or more layers, and the one or more layers can be printed material deposited directly onto the midsole. In some instances, the outsole can include a base layer and an outermost layer. The base layer can include a first printed material deposited directly onto the midsole and includes a first width. The outermost layer can include a second printed material deposited onto the base layer and includes a second width, and the second width can less than or greater than the first width.

An article of footwear includes an outsole, an upper secured to the outsole and defining a foot-receiving cavity and an ankle opening, and a unitary, full-length midsole having a forefoot region, a midfoot region, and a heel region, and configured to be removably inserted into the foot-receiving cavity through the ankle opening. The midsole includes a first cushioning body having a first hardness and a second cushioning body having a second hardness greater than the first hardness. The midsole has a lateral side, a medial side, a forwardmost extent disposed in the forefoot region, and a rearmost extent disposed in the heel region. The second cushioning body includes a lateral segment that extends through the lateral side in the forefoot region, and a portion of the lateral segment of the second cushioning body is closer to the forwardmost extent than to the midfoot region.

An article of footwear may include a sole structure and an upper. The upper may include a first section and a second section and may define a foot-receiving cavity over the sole structure. The first section may be fixed to the sole structure, and the second section may articulate relative to the first section between an access position and a use position, the foot-receiving cavity being more exposed when the second section is in the access position. A magnetic coupling includes a first coupling member that may be operatively secured to the second section of the upper and a second coupling member may be operatively secured to the sole structure and positioned so that the first coupling member couples with the second coupling member by magnetic force when the second section is in the access position.

A device for converting bends of a body to electricity that includes a generator, a bending converter and a connector. The generator includes a stator and a rotor that is connected to a rotational shaft. The bending converter includes a bending arm that has a front side and a back side. The stator and the back side of the bending arm are designed to be fixed directly or indirectly to the body. The rotational shaft is connected to the connector at a first connecting point and the front side of the bending arm is connected to the connector at a second connecting point. When the body bends then the bending arm bend and rotates the rotor relative to the stator.

A sole structure for an article of footwear having a heel region, a mid-foot region, a forefoot region, an interior region, and a peripheral region. The sole structure including a bladder having a chamber including an arcuate segment extending around the heel region, a first segment extending along the peripheral region on a medial side of the sole structure from the arcuate segment to a first terminal end in the forefoot region, and a second segment spaced apart from the first segment across a width of the sole structure and extending along the peripheral region on a lateral side of the sole structure from the arcuate segment to a second terminal end in the forefoot region. A peripheral outsole extends along the chamber and a first cushion is disposed between the first segment and the second segment and is exposed through an opening of the peripheral outsole.
