Article of footwear with adjustable stiffness

This is a snowboard boot designed to let the wearer adjust its stiffness. It uses tensioning systems, likely cables, on the sides of the boot's inner lining. These systems pull on a comb-like structure with flexible fingers, which are located on the outside of the boot, allowing the wearer to change the boot's overall flexibility.

Why it matters: Filed before advanced additive manufacturing could easily create custom flex structures. Modern 3D printing techniques could simplify prototyping and production of the comb body and its flexible fingers, offering new material options.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateCustom flex comb, cable tensioner
