Blaze by the competition in this ultralight cleat. Upper uses SprintSkin II construction, inspired by the adidas Prime track spike. It not only reduces the overall weight of the cleat, but provides support through an external layer of TPU. SprintWeb support frame provides stability during quick changes in direction. Revolutionary SprintFrame outsole is covered by a molded PU sockliner that will keep your feet comfortable throughout the game. Outsole is engineered for balance, with geometric ridges for structure through the midfoot. This gives the perfect amount of football-specific stiffness, while still allowing the forefoot to flex as you accelerate. Heel cup locks your foot in place, so there's no slipping on the field. Triangular TraXion™ studs provide acceleration and straight-away speed, with multidirectional grip on cuts. Good for natural or synthetic surfaces. Wt. 7.7 oz.
