A foamed shoe materialincludes a foamed body divided into a plurality of sections, comprising a fore section, a heel section, and an arch section, and the arch section is located between the fore section and the heel section.

Methods of manufacturing a component at least partially from waste yarns. In some embodiments, the waste yarns may be distributed on a surface and bonded to each other on the surface. The component may be least a part of an upper for an article of footwear, an article of apparel, or a sports equipment article.

This disclosure is related to garments and methods of producing garments that incorporate filling materials that comprise multi-faceted particles, including multi-faceted foam particles, produced by shredding various components associated with, for example, articles of footwear, pads (athletic use pads, industrial use pads, and the like), and the like.

A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

The present invention relates to a manufacturing method for a foam sheet for shoes containing Thermoplastic polyurethane (TPU) powder and recycled Polyurethane (PU) scrap powder, and for an eco-friendly polyurethane foam composition including water foam, firstly the recycled PU scrap powder is mixed with polyol, and then the processing speed in a process is controlled through a side-feeder to react while adding the TPU powder and recycled PU scrap powder secondarily, thereby preventing a rise in viscosity of the raw material, so that even if a larger amount of recycled materials is used than before, it is possible to form foam sheets for shoes, such as shoe insoles or foam packages for shoe uppers, with the same level of product quality as conventional products.

Articles of footwear for sustainable systems are disclosed herein. A modular article of footwear includes a knitted upper component and a midsole component that are removably secured together. Some aspects further includes an exterior sole component that is removably secured to the midsole component and the knitted upper component.

A sole and a manufacturing method of a polymer material are provided. The manufacturing method of a polymer material includes: providing a shoe; performing an alcoholysis reaction of the shoe with a diol to form a polyester oligomer; and performing a polymerization reaction of the polyester oligomer and a polyalkylene glycol to obtain a thermoplastic polyester elastomer. The shoe includes a midsole, an outsole, an upper, a tongue, an insole and an adhesive. A material of the midsole, the outsole, the upper, the tongue, the insole and the adhesive are a polyester material.
