Nike Gripknit is a sticky material that provides better touch to the ball. Micromolding texture works with Gripknit to help form to your foot for even better cleat-to-ball strikes. The wave-like traction pattern is a series of cascading studs, so it engages more surface area of the Air Zoom unit? The full Flyknit upper is engineered for speed.? Obsessed with speed? So are the game's biggest stars. That's why we made these Elite cleats with an improved 3/4-length Air Zoom unit. It gives you and the sport's fastest players the propulsive feel needed to break through the back line. The result is the most responsive Mercurial we've ever made, because you demand greatness from yourself and your footwear.
