Glove-Like Fit The laces feed through interlocking bands in the forefoot. When you tighten the laces, they pull down to help keep your foot comfortably secure inside the shoe. Responsive Court Feel The foam in the midsole feels soft and smooth, while helping to keep you low to the ground and enhancing the sensation of court feel. A top-loaded Air unit under the ball of your foot responds to your force with a burst of returned energy at every step. Generative Traction Computer-generated outsole pattern lets you quickly accelerate, slow down and change direction, helping you feel in control of your movement.
