The Crispi Teton Over the Calf Midweight Sock is purpose-built to deliver superior warmth, padding, and muscle support inside tall, technical hunting and mountain boots. Engineered with an optimized midweight blend of premium Merino wool and durable nylon, this sock naturally insulates against freezing alpine temperatures while rapidly venting sweat to prevent cold clamminess. The extended over-the-calf rise features a specialized elastic stay-up cuff that prevents sagging or bunching during aggressive ascents through rugged terrain. Enhanced, high-density loop cushioning lines the entire footbed, heel, and shin to effectively absorb heavy impact shock and shield your legs from stiff boot-tongue pressure. A seamless flat-stitch toe box eliminates chafing friction points, ensuring a completely blister-free experience during demanding multi-day backcountry expeditions.
