So Warm!

Gave these to my husband for Christmas. He is a pilot for an air ambulance and does day and night shifts. When he is on a cold night shift, these socks keep his feet warm and toasty - he loves them!More > < Less

Bought them primarily to wear around the house on hardwood floors. Lots of cushion. Don't bunch up. Smooth seams. Toasty warm. Not scratchy. I recommend.More > < Less


Best Socks for Cold Feet

12/30/2018 by Christopher

I do outdoor nature photography in Iowa and I’m always looking for socks that are both warm and comfortable, and don’t make my feet sweat. I have finally found that sock.... these are worth every penny! I have purchased 3 pair now. Although it’s recommended to wash in warm water and put in dryer on low, I have been washing them in cool water and letting them air dry. I’m diabetic and very particular about a well cushioned sock to protect my feet. These socks are perfect. My feet don’t get too cold or to hot. Love these socks! Amazing. Most expensive socks I have purchased , but they really deliver on meeting my needs. I have tried dozens of other pricy socks but they didn’t come close to these!More > < 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.
