BACK IN STOCK as of March 5th! this is our second batch already for 2022, when these are gone they are gone.
Surprisingly soft, this is our big boy, these are our heaviest, most insulating, and wicking sock, most likely the warmest sock on the planet (excepting electric)
It is a calf-high sock, great for your taller boots, very thick, quite soft, and well built. Will keep your feet warm and dry all winter long. Ultra-soft bison fiber that has been properly processed, there is no prickly itch from these socks. Thicker and more cushioning than our Pro-gear socks.
This sock has a terry loop padded foot bed, and terry loop gentle ribbed construction all the way up the calf with just enough spandex to hold it above your 12" boot top...but not enough to cut down circulation. Nylon over-plaited in the toe and way up past the heel for long smooth wear.
**This is a performance sock designed to go inside footwear. Not intended to be worn as house slippers.**
We gave a pair of our Trekker boot socks to survival expert Leon Pantenburg, and here is his review.
Sock Sizing
Socks should fit as well as any of your other garments. The heel should sit on your heel and not under it as in a sock too small, nor half way up your Achilles as in a sock that’s too large. 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
The toe seam should lie flat along the top of your toes, not above or below.
Taut Across the Foot
Socks should be taut across your foot with no sagging material.
