Cold feet can end a great ski day fast. The DryGuy Boot Glove slips right over your ski boots to lock in warmth and shut out the wind - so you stay on the mountain longer and actually enjoy it. Developed for Alaska's brutal Arctic conditions, this neoprene shell isn't messing around. It retains up to 53°F (12°C) of warmth inside your boot, which is the difference between comfortable runs and calling it quits at noon. The windproof, waterproof 4.5 mil N2S neoprene outer shell fits snugly over standard ski boots, and the adjustable Velcro heel strap keeps everything locked in place. Once it's on, you'll barely notice it's there - until you remember your feet aren't freezing. If cold weather has been cutting your ski days short, this is a simple fix that actually works.
