Our polyurethane footbed provides superior shock absorption with an additional layer of open cell construction for improved air circulation. Known for its lightweight properties, EVA is a special polymer that provides excellent cushioning. 100% rubber for superior abrasion resistance and pentagonal lugs for maximum surface contact. The DLE-01 last was designed to be an extension of the foot with superior forefoot and heel capture, stability and a more anatomical shape for comfort. The additional space in the toe box allows the foot to naturally react when bearing a heavy load or changing directions laterally in high intensity environments.
