The Darn Tough Mountaineering Over-The-Calf Heavyweight Full Cushion Sock (Style 1955) in Smoke is a unisex OTC-height mountaineering sock with heavyweight full cushion density throughout the footbed and leg — the warmest platform Darn Tough builds, designed for alpine conditions and extended time in mountain boots. The over-the-calf cuff sits below the knee to protect the shin against boot contact, and True Seamless toe construction closes the front of the sock smoothly so there’s no seam bump at the toes during long climbs.
The merino-heavy knit handles moisture wicking and temperature regulation across cold summit pushes and warmer approach miles, while the nylon percentage keeps the sock durable against mountain boot contact, crampon straps, and repeated wear. Reinforced high-wear zones at the heel and toe handle the rubbing that thinner socks can’t, so back-to-back alpine days stay blister-free. Smoke is a muted gray colorway that pairs with every mountain kit and winter layering.
Darn Tough knits every pair in Northfield, Vermont and backs them with an unconditional lifetime guarantee.
