AI Technical Summary
Existing footwear kits with detachable heels fail to provide adequate walking comfort in low-heel states, particularly due to insufficient cushioning and impact absorption.
A footwear kit design featuring a sole with an upwardly inclined curved portion supporting the MP joint, higher cushioning in the second heel, and a sole structure that maintains consistent shape between high- and low-heel states, enhancing impact absorption and reducing foot strain.
Improves walking comfort in low-heel states by increasing cushioning and impact absorption, allowing for easy transition between heel heights without structural changes, and reducing the need for multiple lasts, thus lowering manufacturing costs.
