Skiing is one winter"s most fun activities, but even in cold weather, skiers typically sweat a lot. Ski boots and socks have long been known for becoming wet, cold and uncomfortable which can ruin the fun and bring about real problems. MOISTURE IS THE ENEMY Wet socks are a skier"s worst enemy, especially in cold or freezing temperatures. Wet socks pull heat away from the skin 23 times faster than dry socks; this can reduce skin temperature so rapidly that wet feet become painfully cold and are much more susceptible to frostbite and chafing. Staying dry is critical for remaining warm, comfortable and safe in cold weather. DRYMAX SKI SOCKS KEEP FEET DRY and COMFORTABLE. The laws of physics dictate; no single fiber technology can attract and repel moisture at the same time. To overcome this, Drymax Ski socks utilize two different fiber technologies interwoven together. This Dual Layer design creates a self-contained Moisture Removal System keeping feet dry and comfortable in cold conditions. This self-contained system is very important because the ski boot"s enclosed environment gives moisture no chance of evaporating.
