Survival Over-the-Calf Socks

Made in the USA with U.S. Grown Alpaca

The Survival Over-The-Calf Alpaca Sock is designed for long days, harsh weather, and serious mileage on foot.

Heavy-weight, fully cushioned, and climbing several inches higher than a standard boot sock, it delivers maximum coverage and warmth from toe to just below the knee.

Alpaca’s natural insulating power keeps feet comfortably warm without getting clammy, while the dense terry loop interior traps heat and channels moisture away from the skin. Whether you are breaking trail in deep snow, glassing on a windy ridge, or working outdoors from dawn to dark, this is the sock to reach for when conditions are at their toughest.

These socks stay put all day long—no sliding, sagging, or constant readjusting, even when worn under heavy-duty boots or layered long underwear. The fit is snug but not constricting, designed to stay up and stay comfortable through constant movement.

High-wear zones—heel, sole, and toe—are wrapped in a heathered royal blue nylon exoskeleton for extra durability and protection where it’s needed most. Inside, a built-in elastic arch band gently hugs the midfoot, improving fit, reducing fatigue, and helping the sock move with the foot instead of against it.

Alpaca’s unique fiber structure means the terry loops insulate, wick, and breathe all at once. Feet stay warm, dry, and fresher for longer, even in heavy boots and fluctuating temperatures. That makes the Survival Over-The-Calf an ideal choice for cold-weather work, winter sports, hunting, and any multi-hour adventure in demanding terrain.

78% U.S. Alpaca, 20% Recycled Nylon, 2% Lycra
