Nike 6.0 Mavrk Shoes: The Nike 6.0 Mavrk combines an old-school sole with an action-sport performance upper for a shoe that you can rock anywhere, on or off the board. The vulcanized sole sports smooth looks and flexibility, while the herringbone tread for positive traction gives a serious board grip. With a suede upper with a toe cap and u-tongue for durability and fitted comfort, this shoe is the ultimate breathable footwear.
