Combining a super-comfortable anatomical fit with a warm and durable merino-blend fabric, Icebreaker's Ski+ Light Over the Calf socks are lightly cushioned and designed for all-day performance on the mountain. Their Ski+ sock construction features support zones in the ankle and over the Achilles and instep to keep the sock in place, sculpted cushioning to maximize fit and comfort, and a breathable forefoot zone for improved ventilation. The seamless toe closure reduces bulk and helps prevent blisters when hiking or touring in the backcountry.
