Rubber sole Max Air cushioning helps to dissipate the hard forces of impact and give you a bouncy, responsive sensation. It runs the shoe's full length and is shaped to follow where your foot hits the court. Breathable mesh provides a lightweight, conforming fit. Reinforced stitching along the sides helps the shoe fit snugly. The durable rubber outsole has a classic herringbone traction pattern front to back. The rubber is split and partially cut out under the arch to help reduce weight and let it flex. Molded foam midsole is lightweight, resilient and helps smooth the transition from heel to toe. The lightweight, reinforced mesh upper keeps you contained all around, from the webbing that harnesses your forefoot to the external molded pieces that lock in your heel.
