Waterproof, breathable shoe and method for manufacturing a shoe

This invention describes a shoe designed to keep feet dry from outside water while allowing them to breathe. It achieves this by using a waterproof, breathable lining that covers both the top and bottom of the foot. The shoe also features a special sole with internal air channels that connect to openings on the side of the sole, letting air circulate and moisture escape.

Why it matters: Since 2010, advancements in footwear manufacturing, particularly in 3D printing and advanced molding techniques, have made creating complex, multi-layered sole structures with integrated air passages more feasible and cost-effective. This could enable more precise and efficient production of such a shoe.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSpecialized footwear manufacturing, multi-layer sole molding.
