The Darn Tough Style 1954 Women’s Mountaineering OTC Extra Cushion is a women’s over-the-calf merino wool sock knit with maximum cushion density throughout the foot. OTC height extends above the calf to protect against mountaineering boot tops and gaiters, and the heavy cushion absorbs impact on steep descents, glacier travel, and technical terrain. True Seamless toe fusion removes the toe seam that raises hot spots across long summit days.
The Midnight colorway a deep blue-black that reads neutral across most outfits. The 80% merino wool blend is the heaviest wool build in the line — warmer, denser, and slower to compress than midweight — and holds thermal regulation when wet, which matters on snow, ice, and alpine weather. Sized specifically for women’s feet so the cushion stays placed correctly inside a mountaineering boot.
Darn Tough is family-owned and knits every pair at their mill in Northfield, Vermont. Lifetime guarantee covers the mountaineering line like every other pair in the catalog.
