Surprisingly Soft and Seriously Warm
Our Trekker Boot Socks are our heaviest, most insulating, and most wicking sock. We’re sure these are likely the warmest socks on the planet. Well, the warmest that aren’t electric but they are silly and pretty impractical!
Trekker Boot Socks = Workhorse Gear
Designed to be your go-to extra heavyweight boot sock, our Trekkers are extremely thick, quite soft, and well built. Created with ultra-soft bison fiber, these socks are thicker and more cushioning than our Pro-gear socks. We use only properly processed bison fiber that is 100% free from stuff that will make the socks itchy or abrasive.
Our Trekkers feature a terry loop padded foot bed and are over-plaited in the toe, heel, and slightly up the leg to make sure your feet will be comfortable all day long.
Despite the extra cushioning and tough construction, these performance designed socks are intended to be worn with footwear. They are not intended to be worn as house slippers. You certainly can, but wearing them on concrete and abrasive surfaces will impact wear.
Trekker Boot Socks are awesome, but don’t just take our word for it!
We gave a pair of our Trekker boot socks to survival expert Leon Pantenburg, and here is his review.

Socks should be flush against your foot with no extra material sagging. The toe seam should lay flat across the top of the toes.
Sock Heel at Your Heel
The sock heel should sit on your heel, not under it or above it.
Flat Toe Seam
