Icebreaker designed their Ski+ Medium Over the Calf socks with a super-comfortable ergonomic fit and an incredibly warm and durable merino fabric blend. These socks are cushioned for all-day performance in ski or snowboard boots, featuring support zones in the ankle, Achilles, and instep to keep them in place. They also have sculpted cushioning to improve fit and a breathable forefoot zone for improved ventilation. The seamless, asymmetrical toe box reduces bulk and prevents blisters when walking, hiking, or ski touring.
