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.

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.

Systems and methods of manufacturing a shoe outsole are provided wherein at least a portion of the resulting shoe outsole includes embedded particles. An example method includes applying adhesive to at least one region of the shoe outsole, depositing selected particles onto the adhesive to provide the shoe outsole with a first coat of particles, and at least partially curing the adhesive. The method continues by applying additional adhesive over the first coat of particles, depositing additional particles onto the adhesive to provide the shoe outsole with a second coat of particles, and at least partially curing the subsequent application of adhesive.

A shoe sole that is less likely to feel push-up on the sole at the time of landing and suppresses pronation to enable quick weight movement in running or jogging, while being widely available in sports requiring weight movement such as golf, tennis, basketball, soccer, and skateboarding, as well as that is lightweight, has good wearing comfort and provides stable walking even in using on the street or walking. The shoe sole includes a shoe sole main body made of a flexible material, and a plate made of a material having a flexural modulus higher than a flexural modulus of the flexible material constituting the shoe sole main body, in which at least two of the plates are included in the shoe sole main body.

Compression molded foam articles are provided having a closed cell foam structure comprising a plurality of cells having an anisotropic cell shape. The disclosed compression molded foam articles can be used as components or parts of a variety of articles, including articles of footwear and athletic equipment. Methods are disclosed for making the disclosed compression molded foam articles from a foamed preform having an elastomeric closed cell foam with substantially isotropic cell shape. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

A sole structure for an article of footwear includes an outer sole element, an inner sole element, and a membrane. The outer sole element has a first top surface and a recess formed in the first top surface. The recess is defined by an inner peripheral surface extending from the first top surface. The inner sole element is disposed within the recess and has a second top surface and an outer peripheral surface extending from the second top surface. The outer peripheral surface is spaced apart from and opposing the inner peripheral surface of the outer sole element to form a channel between the inner sole element and the outer sole element. The membrane is joined to the first top surface of the outer sole element to sealingly enclose the channel and define a chamber.
