Drymax Cold Weather Running Crew, Red, W10-12, M8.5-10.5

In cold or freezing temperatures, moisture is the skin's worst enemy. Moisture pulls heat away from the skin 23 times faster than air, and can reduce skin temperature so rapidly that wet feet feel painfully cold. Wet skin makes the feet much more susceptible to frostbite and Non-Freezing Cold Injury. Staying dry is critical to remaining warm, comfortable and safe in cold weather and no sock has proven to keep feet drier than drymax technology socks. The wind chill factor often causes the front part of the leg to become the coldest; therefore a third layer of drymax fiber insulation was added along the Cold Weather sock's leading edge.
