Combining a super-comfortable anatomical fit with a warm and durable merino-blend fabric, our Ski Medium Over the Calf Peaks socks are fully cushioned and designed for all-day performance on the mountain. Our 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.
