Adidas X Crazyfast Messi.1 are a quicksilver tribute to Messi's trophy-laden career. These X football boots have a semi-translucent Aeropacity Speedskin upper with reinforcements only where they're needed, producing a super-lightweight look and feel. The firm ground Speedframe outsole includes two additional studs and an Aeroplate inlay for extra acceleration and energy return. An adidas PRIMEKNIT collar keeps you locked in. Made with a series of recycled materials, this upper features at least 50% recycled content.
