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. 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 biggest stud is the same height as our traditional middle studs, so traction is not compromised. We paired the wave-like traction with evolved chevron and blade studs to help you stop when making quick cuts. The Gripknit, Atomknit and Flyknit combine to form the thinnest Mercurial upper to date, bringing you closer to the ball and lessening break-in time. Obsessed with speed? So is Kylian Mbappe. That's why we made these Elite cleats with an improved 3/4-length Air Zoom unit. It gives you, and Kylian, 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.
