The Darn Tough Style 1955 Mountaineering OTC is a heavyweight over-the-calf sock with high-density cushioning throughout the entire sock. It’s the warmest, most cushioned sock in Darn Tough’s mountaineering line. True Seamless toe construction fuses the toe seam flat so it doesn’t become a pressure point inside stiff boots.
This is the sock for mountaineering, ski touring, ice climbing, and winter boots that rise above the calf. Over-the-calf height protects the full leg from boot-top rub and cold, the merino wool content regulates temperature across cold and warm conditions and keeps insulating even when damp, and the heavy cushion absorbs impact from stiff-soled boots across long days.
Darn Tough still knits every pair at their family-owned mill in Vermont with yarns sourced from America and around the globe. The lifetime guarantee applies — wear them out on the mountain and Darn Tough replaces them.
