Chimney structures for apparel

This invention describes a form-fitting foot covering, like a sock, that has built-in chimney-like channels. These channels are designed to move heat and moisture away from the foot and out through the top opening of the covering. The chimneys are constructed from elongated supports connected by braces, potentially with a covering on one side.

Why it matters: Filed before advanced textile manufacturing and flexible material integration. Modern 3D knitting and material science could now create these structured chimneys more seamlessly and comfortably within apparel.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateElongated supports, braces, textile covering
