Nike Gripknit is a sticky material that provides better touch to the ball. It covers the first 2 laces, taking up more surface area so you have more room to control the ball. It molds to the shape of your foot and gives you equal grip in wet or dry conditions. Asymmetry in the collar and heel provides comfort. Soft elements in the heel make for an easy break-in process and helps reduce irritation and pressure without compromising stability and structure. Tri-star studs (the highest number and biggest variety of any Nike cleat) work with forefoot flex grooves to help unlock change of direction. See the squiggly line on the outsole? It matches your typical on-field movements, which push forward then zigzag before a strike.
