Heel studs provide traction and stability when braking. Toe-off center studs give you traction during explosive starts.The upper is made of Vaporposite+, which combines a grippy, grid mesh with a premium material for optimal ball control at high speeds. The material provides a tactile feel across the surface of the upper. It’s soft, but stable and wraps tightly around your foot, giving you a more natural on-ball feel when dribbling, passing or scoring.
