Article of footwear

This is a shoe featuring a unique upper part designed to expand in all directions when stretched, which could offer improved comfort or fit. This special upper is constructed from three distinct layers of material that are pressed together in a mold to form its intricate, expanding three-dimensional structure.

Why it matters: Computational design tools for complex auxetic geometries and advanced material composites suitable for multi-layer compression molding have significantly matured since 2018, making the precise manufacturing of such a footwear upper more achievable.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedAuxetic material design, industrial compression molding, multi-layer bonding
