Have a better run with the Injinji Ultra Run No-Show CoolMax Sock keeping your attention from drifting toward your feet. The separated toe design encourages proper foot alignment while protecting your skin from forming blisters between each toe, maximizing your efficiency. CoolMax material wicks away perspiration and allows air to flow to keep your foot cool and minimize chafing. The sock has an extended heel tab to protect the back of your ankle from the abrasive nature of your shoe, as well as padding underfoot and throughout the toes to cushion your foot against the impact of each stride.
