I’ve tried many , many “cushion” socks in the past, and have some still in my sock area, but even though these cost a bit more, I have ever come across any sock as comfortable as these. I’ve actually worn out 6-7 pair of these socke because I wear them every day. They’re never too hot in the summer here in Texas, nor do they let in the cold we get in winter. They breathe just right, never “sweaty” either. Putting them on, the tops are just stretchy enough to slide right on, no tugging or struggle involved, and they slide right off just as easily, and..they don’t sag. That’s a lot to say about these socks, but in this cas, you really get your moneys worth. I wear them out in the ball of my foot, as that’s where all the pressure is when walking. If these get that part more re-I forced, they would be absolutely perfect. Thanks United by blue, this is the stuff you’re made of. Thanks again, and keep it up! David C. Bedford, Texas

A blend of bison down and merino wool makes the Ultimate American Sock a warm, cushy, and durable way to keep your feet snug and dry. Completely Made in the USA—from the North Dakota materials to the Pennsylvania packaging—these socks help our country’s environment, too. For every pair sold, the company cleans a pound of litter from our nation’s waterways.

United By Blue

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. more Their Story
