Running in cold weather isn"t always fun. Runners have learned that wearing several layers of clothing offers the best protection. But getting dressed in layers of warm clothing inside a warm house often causes one to perspire. Starting a cold weather run with damp clothing means that the runner will get cold – quickly. 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 not only to frostbite, but also to blisters. The Drymax Cold Weather Running Socks have a special Dual Layer Moisture Removal System. This system instantly moves moisture from the skin, through the inner Drymax layer to the outer absorbent layer, keeping feet dry. Staying dry is critical to remaining warm and comfortable in cold weather.
