A common sock misconception in the winter sports world is that you want the thickest ones possible to keep extra warm out on the mountain. While that isn't a completely unreasonable line of thinking, super thick, cushiony socks aren't always better. You want very little to be coming between you and your boot. If your boot fits right, it should be an extension of your body, and your sock should fit snuggly in between. Thicker socks can lead to pinching, bulging, and folding, which can lead to pain and an awful day. While this Smartwool Performance Ski Zero Cushion sock lacks cushioning, it's got tons of other redeeming qualities. It hits just over the calf and the fabric is equipped with indestructawool technology for enhanced durability. Less cushion makes it have a more performance-oriented fit and helps it stay in place, unbunuched all day. Additional Shred Shield technology reduces wear and tear in the toes and specific body-mapped mesh helps with breathability.
