AI Technical Summary

Technical Problem

Existing shoe air cushions are insufficient in terms of user experience, stability, and comfort when considering the stress distribution in different areas of the sole. Traditional designs have failed to comprehensively improve cushioning and support performance.

Method used

A footwear air cushion designed to conform to human biomechanics is constructed by setting multiple chambers within the air cushion body and filling different chambers with fillers of different hardness. Polyurethane is used as the shell and foaming composition, and the foaming process is controlled to form hardness gradients in multiple regions, ensuring a smooth transition between cushioning and support performance.

Benefits of technology

It improves the stability and comfort of shoe air cushions during landing, provides better cushioning and support, and enhances the user experience.
