Free 4.0 V4 'Wolf Grey'

The Nike Free 4.0 V4 is a neutral running shoe specifically engineered for competitions and training on the road. This 'Wolf Grey' iteration balances breathability and support in herringbone-patterned mesh and neoprene with a synthetic overlay. While an open heel structure promotes freedom of movement, a molded toe guard protects the high-risk area. Phylon midsole cushioning and a flexible carbon rubber outsole complete the underfoot.
