The Nike x CORTEIZ Air Trainer Huarache's exterior is defined by its exoskeletal structure that keeps the shoe lightweight while providing necessary support. The signature neoprene sleeve, good for a snug fit, is topped with a rubber huarache patch, "air huarache by CRTZ." A tonal swoosh is stitched into the toe box, with the c star, Alcatraz on the midfoot strap, and "NIKE RTW" on the back of the shoe.
