Style#: CD4982-900 Full-length Nike Zoom Air cushioning is articulated to follow the shape of your foot, providing a great heel-to-toe transition. An additional Zoom Air unit gives you extra bounce on court. Lightweight, multilayer mesh uses minimal backing material for less stiffness and a broken-in feel. A sockliner insert sits over the Nike Zoom Air cushioning, adding a thin layer to help smooth the underfoot feel without compromising the performance. 4-way directional Flywire cables provide targeted stability and on-the-fly lockdown. They relax when you??re not in motion, but when you need them to perform they deliver.
