The Craft XC Race Sock can't guarantee you a spot on the podium, but it can guarantee your feet will be cozy when you get there. The midweight sock delivers a dry, well-insulated and ventilated environment while creating a no-slip, non-elastic cradle around your foot. This prevents blisters and reduces friction, so you can go faster and farther before you get sore feet. Craft socks are itch-free, preshrunk and plated with micro-fiber polyester on the outside of the sole for durability.
Bottom Line: It'll make you more comfortable, you have to get faster on your own.
