The Smartwool Ski Full Cushion Over The Calf Sock is a tall sock for skiing. The incredible blend of Merino Wool, nylon, recycled nylon, and elastane provides next-to-skin comfort and regulates temperature. The full cushion and body-mapped zones don't just provide warmth, they add an extra layer of padding at the bottom of the foot and the front of the shin where ski boots put pressure, while the back of the calf is thinner and more breathable. Sock, ski boot, skis. All that's left is to get on the ski lift.
