The Smartwool Medium Pattern Ski Sock - Men's is an over-the-calf sock for skiing. This cozy sock is constructed with a yarn blend of Merino Wool, nylon, and elastane, offering next-to-skin softness, durability, warmth, and breathability. It wicks moisture away from the skin and dries fast, and the medium cushion is placed underfoot and at the front of the shin to soften between you and the ski boots. These tall boys feature the 4 Degree elite fit system, preventing them from bunching up or slipping around while spending the day on the slopes.
