Nike is branching out into a new and unexpected market with the release of its first ever removable sole for the Össur Flex-Run prosthetic running blades. The new shoe, called the Nike Sole, was made in collaboration with triathlete Sarah Reinertsen.
The Sole is a minimal shoe designed to slip onto the blades. It has an outsole, a midsole and a specially designed material called Aeroply, which allows it to grip the carbon fiber of the prosthetic blade. Its designers claim the shoe can increase stability, normalize stride length and improve forward energy return for a more efficient gait progression.
