Nike is giving her a boost, however, with a lightweight, durable composite sole that slides easily over her carbon-fiber running blade. Because options for prosthetic soles are limited, particularly for ersatz limbs that aren’t shaped like a human foot, Reinertsen had to cobble her own using the outsole of a traditional running shoe. The sportswear giant worked with both Reinersten and Össur, which manufactures the Flex-Run blade, to engineer the “Sole,” a shoe that offers a tighter grip, increased stability, and a more predictable advantage on the track."
