The Darn Tough Women’s Mountaineering Over-The-Calf Extra Cushion Sock (Style 1954) in Midnight is a women’s expedition and mountaineering sock with the densest full-cushion footbed Darn Tough builds — thick terry loops across the entire sock for maximum warmth and shock absorption on high-altitude climbs, winter ascents, and alpine trekking. The over-the-calf shaft rises above the top of mountaineering boot cuffs so there’s no boot-edge bite against bare skin during long steep climbs. True Seamless toe construction closes the front of the sock smoothly, so there’s no seam rub inside tightly-laced expedition boots.
The knit — 72% Merino Wool with Nylon and Lycra Spandex — leans heavily merino-forward for maximum moisture wicking and temperature regulation across sub-zero summits and steep sweaty climbs, and the nylon percentage carries the sock through season after season of crampon and boot-buckle friction. Targeted arch support hugs the midfoot so the sock stays locked in through technical terrain. Midnight is the deep navy alpine colorway that pairs with winter mountaineering kit.
Darn Tough knits every pair in Northfield, Vermont and replaces any pair that wears, tears, or develops holes under its lifetime guarantee.
