Running shoes, hiking shoes and boots, snowboard boots, alpine boots, hiking boots, and the like, having waterproof/breathable moisture transfer characteristics

This invention describes a special fabric designed to manage heat. It's a nonwoven material made from synthetic fibers that have been chemically treated on their surface. This treatment allows the fabric to absorb and release heat as needed, providing enhanced thermal properties.

Why it matters: Since 2014, advancements in material science and textile manufacturing, particularly in microencapsulation and surface treatment technologies, may have made the production of such phase-change treated fibers more efficient or cost-effective. This could enable broader application in performance footwear.
