Nike Mercurial Superfly 9 Academy Artificial Ground Cleats Instantly tilt the field in the bold design of the Superfly 9 Academy AG. 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. For the first time in our history, 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—whether you're scoring goals, being first to the ball or going by defenders. 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. Flyknit wraps your ankle in soft, stretchy fabric for a secure feel. A redone design improves the fit, so that it better simulates the foot. The result is a more contoured toe box and better lockdown in the heel. The 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.
