This Nike Mercurial Superfly 8 is designed with a revolutionary “Vaporposite” upper created by four layers called Duragon WT, Engineered Mesh, Titan Synthetic and Avail Q Lining. The result is a unique fit and support with very good grip on the ball. Flyknit compression material is placed at the ankle, which helps create a comfortable feeling, optimal support and increased flexibility. Strategically placed studs, which with their angular shapes and length, act like claws during acceleration and changes of direction. The Dynamic Fit high sock is reinforced compared to previous models, it offers optimal support for the ankle and foot.
