Designed for the quickest-hitting playmakers in the game, the adidas X 15.1 FG/AG 'Iron Black' offers a lightweight construction, aggressive firm-ground traction and textured touch for more control and creativity. The upper is made of X-SKIN material, with a tacky surface for more accurate passing, dribbling and shooting on goal. An X-CAGE exoskeleton provides structure and support around the foot, stabilizing it without weighing it down. Underneath, X-CLAW cleats provide reliable field grip.
