The Finer Details Nike has developed an all-new Zoom Air unit. It sits in the plate and provides an additional level of springy underfoot feel that helps you move faster on the field and create separation when it matters the most The speed cage inside of the structure is made of a thin but strong material that secures the foot to the outsole without adding additional weight for optimal lockdown. Unique traction pattern offers supercharged traction with quick release to create separation. A redone design improves the fit, so that it better simulates the foot. Nike did this by conducting multiple wear tests on hundreds of athletes. The result is a more contoured toe box and better lockdown in the heel.
