Help Junior squeeze in a few extra runs before his toes start to freeze and his lips turn blue. SmartWool's Ski Racer Socks lock in plenty of warmth for long days on the hill and have just enough extra padding in the front to keep your kid's ski boots from eating his or her shins alive. The merino wool and nylon blend offers the best of both worlds--the added durability of synthetic fibers and the comfort and odor-resistance of wool.
