Soft shell boots and waterproof/breathable moisture transfer composites and liner for in-line skates, ice-skates, hockey skates, snowboard boots, alpine boots, hiking boots and the like

This invention describes soft-shell boots or lifestyle footwear designed to keep feet dry and comfortable. It uses a layered system starting with moisture-transferring fabrics like polyester or cotton, followed by an antimicrobial nonwoven material with specially shaped fibers. The outer shell can also be treated with advanced waterproofing or temperature-regulating technologies.

Why it matters: Since 2022, advancements in textile manufacturing and material science, particularly for specialized fibers, nanotechnology, and phase change materials, may have made these complex material systems more cost-effective or accessible for integration into footwear.
