Flyknit wraps your ankle in soft, stretchy fabric for a secure feel. A redone design improves the fit, so that it better simulates the foot. The result is a more contoured toe box and better fit in the heel.The upper is made of Vaporposite+, which combines a grippy, grid mesh with a premium lining for optimal ball control at high speeds. The lining provides a tactile feel across the surface of the upper. It’s soft, but stable and wraps tightly around your foot. The pliability offers a more natural on-ball feel for dribbling, passing or scoring.The speed cage inside of the structure is made of a thin but strong material that secures the foot to the outsole without adding weight.
