Contact-free pressure point protector for feet consists of air/water filled chamber on rubber tape as buffer between foot and shoe upper

摘要

The device consists of an air/water-filled rubber chamber, a connected rubber tape with hook-and-loop fastener, and a semi-rigid plate to prevent slipping. The chamber acts as a buffer between foot and shoe upper, and its cover adapts itself to foot and shoe upper shapes. This results in even average contact pressure.
