Nike Footwear Nike Gripknit is a sticky material that provides better touch to the ball. It takes up more surface area, so you have more room to control the ball when dribbling at high speeds or finish a play with a shot on goal. It molds to the shape of your foot and gives you equal grip in wet or dry conditions for a sculpted, track spike-like fit. The wave-like traction pattern is a series of cascading studs, so it engages more surface area of the Air Zoom unit while also providing the appropriate amount of grip. The full Flyknit upper is engineered for speed. Atomknit, an incredibly lightweight and strong Flyknit, on the sides tapers weight and provides support.
