It's loaded with a Zoom Air unit and flexible NikeSkin up top for exceptional touch, so you can dominate in the waning minutes of a match—when it matters most. Fast is in the Air.Welcome to the Field, ZoomFor the first time in our history, Nike has developed an all-new Zoom Air unit. It sits in the outsole 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—whether you're scoring goals, being first to the ball or going by defenders.Drive Your SpeedThe 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.Dig In, Take OffBased on Nike Sports Research Lab analysis of player movements, the rubber outsole is designed to provide multidirectional traction on street, court and indoor surfaces.Improved FitFlyknit wraps your ankle in soft, stretchy fabric for a secure feel. A redone design improves the fit, so that it better simulates the foot. We 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.Barefoot FeelThe upper has NikeSkin, a soft and flexible mesh material linked together by a thin coating. It helps provide ball control and truly gives you a feeling of barefoot soccer.More Details For use on street, court and indoor surfaces Cushioned insole
