Innovating Footwear through Shape Memory Alloy In a fascinating intersection of material science and footwear design, researchers are experimenting with Shape Memory Alloy (SMA) to solve long-standing issues in sneaker accessibility. Often called muscle wire or nitinol, this material possesses the unique ability to return to a pre-set form when exposed to heat. By testing straight wires and coiled springs, designers are looking to create adaptive footwear solutions. Addressing Accessibility and
