The XC-72 pushes its classic sources of inspiration even further into unexplored territory, with a time-bending design inspired by the speculative technological optimism of 1970s concept cars. The sneaker has a vertically split outsole with two hard ground traction designs the XC15's 'gripper' and the 375's studded pattern. Stability heel clip featuring 620s herringbone outsole pattern, single later microfiber tongue, and squared toe shape inspired by 1970s concept car designs.
