Just Wgat I Was Looking For

2/13/2019 by Helen

Purchased these socks for my husband to have during deer hunting season in late November. He was very impressed with the fit, comfort, and performance. The socks kept he feet warm and dry then, and continue to do so as he wears them each time he has had to shovel and throw snow. Great investment!More > < Less

These socks are super warm but breathable. Not itchy at all. I like the heathered color; it seems to blend with everything I wear.


He loves them!

Best socks ever

I bought these socks for my husband who is a diabetic with neuropathy in his legs and feet and are often cold. He loves these socks that help hold the heat in and soft as he walks. They may cost a little more than some store socks but you cannot put a price on comfort. Will stay a customer. Thank youMore > < Less

About United By Blue

Bison Built

When you think of bison, you probably picture large, furry animals roaming America’s plains. What you might not know is that bison down is soft, warm, and wicks moisture, too. What better way to use this wonder fiber than in thick, cushy socks that are American from materials to mission?

The Ultimate American Socks are plush, warm, and even microbial—meaning you can wear a pair a few times before washing. Padded, reinforced toes and heels add to their durability.

Every step of making these ultra-American socks takes place in the U.S., starting with bison ranched in North Dakota. From there, the yarn is spun in Massachusetts and knitted in Iowa. The packaging is made in Pennsylvania.

United by Blue is so committed to our country that these socks even benefit American conservation. For every pair sold, they remove one pound of litter from our waterways.

Every time you pull on these cozy socks, take pride in preserving American manufacturing as well as our shining lakes and streams.
