Go farther, stay comfortable. Designed for long days hiking in extreme terrain and conditions. Easy on the foot, but tough on cold, sweat, heat, moisture. Slightly lighter weight than our Trekker socks, but still "Seriously warm-Surprisingly soft", our newest extreme sock, that will keep your feet warm and dry all winter long. Ultra-soft bison fiber that has been properly processed, no prickly itch from these socks. Thicker and more cushioning than our Pro-gear socks.
This sock has a terry loop padded footbed, and lighter ribbed construction all the way up the calf with just enough spandex to hold it above your 10" 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.
Superior breathability, temperature regulation, and natural odor resistance!!
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. If you wear a wide shoe size (E+), consider sizing up.

I work outside sometimes in bad conditions and leave a pair of these in my work bag for when I have to deal with snow or want a warm pair of socks to change into. So far they have been excellent.
You will find the rest of the wool in your dryer vent, so hang dry.
This was a gift for my brother. Weather in NYC has been warmer than usual, so he hasn't worn the socks yet.
I have always loved merino wool socks for their softness but combine them with Buffalo wool and they are really a soft touch. I have purchased four pairs snd love them all.
Got these as a Christmas gift for my husband. They are so comfortable and warm (we live in Northern Colorado where "warm" is essential) they are now his favorite socks.
comfy, warm, and thick. keep in mind for size of boots / shoes. time will tell for durability but so far I am happy with these socks.
Fluffy, fuzzy, comfortable, keeps my feet dry and warm in the worst weather. A must for outdoor winter activities!
I really appreciate how nice they look and how well they wear. Great socks! Great gift too!
