Icebreaker designed the men’s Ski+ Medium OTC (Over The Calve) Glade Socks with a super-comfortable ergonomic fit in an incredibly warm 68% merino wool fabric blend. These socks are anatomically cushioned for all-day performance in ski or snowboard boots. They feature support zones in the ankle, Achilles, and instep to keep them in place and prevent bunching. Breathable forefoot zones enhance ventilation, keeping your feet fresh in your boots. The seamless asymmetrical toe box decreases bulk, preventing toe blisters.
