Why Choose the Crevasse Sock: Warmth underfoot: Full Merino-wool cushioning adds comfort on cold-weather outings. Reinforced where it matters: Cordura® at the heels and toes helps protect high-wear areas. Comfort over distance: A flat-linked toe seam helps reduce rubbing inside your boots. Supportive fit: Elastic grip sections and an in-turned welt help the mid-calf sock sit comfortably. Helps manage moisture: Ventilation channels and a fast-wicking sole support comfort during activity. Perfect For: Cold-weather walks, hikes and other outdoor days when you want cushioning, warmth and a comfortable fit inside your boots. Why a Merino Wool Blend? Merino wool brings softness and warmth next to the skin. In the Crevasse Sock, it works alongside cushioning, ventilation and a wicking sole to help keep your feet comfortable on long outings. As featured in Grough: “The Keela socks kept my feet warm and dry, and comfort over extended distances was good.”
