A sole structure for an article of footwear includes a unitary cushioning component comprising a plurality of scrap foam pieces configured as a plurality of different polyhedron shapes and a resin binder securing the scrap foam pieces to one another. The sole structure may comprise a midsole including an outer shell defining a central cavity. The cushioning component may be disposed in the central cavity as a core of the midsole. A method of manufacturing an article of footwear cutting the scrap foam body into pieces, mixing the pieces with a resin binder, and compression molding the mixed pieces and resin binder in a mold to form a cushioning component of a sole structure of the article of footwear.

Eco-friendly method of manufacturing shoe material, semi-finished, and foamed shoe material made thereby

A method of manufacturing the foamed shoe material and semi-finished product including the following steps. Step S1: a foamable material is injected into a cavity of a blank mold to solidify, thereby generating a semi-finished product of the shoe material and a runner waste that are unfoamed. The runner waste could be shed for reusing directly as the foamable material without a granulating process. Step S2: the semi-finished product is cooled down and put into a cavity of the foaming mold, and the semi-finished product is evenly foamed in the cavity of the foaming mold to obtain a shoe material wherein the waste generated during the method of manufacturing the foamed shoe material could be effectively reused, and the yield rate of the shoe material thereby enhanced.

Sports Shoes and Methods for Manufacturing and Recycling of Sports Shoes

A sports shoe includes an upper wherein a majority by weight of the upper is made from a thermoplastic base material and a sole wherein a majority by weight of the sole is made from the same thermoplastic base material. The sole and the upper are individually fabricated and joined to each other. The thermoplastic base material includes at least one of the following materials: thermoplastic polyurethane TPU, polyamide PA, polyethylene terephthalate PET, or polybutylene terephthalate PBT.
