Where are these socks in women's sizes???? Won't be ordering since men's socks are just too big.


Would not buy again

My son-in-law loved the socks for Christmas and was excited about the story behind them but after wearing only two times there is a hole in the toe. What a shame - wanted to buy more.More > < Less

i am very disappointed w/ these socks! they're nowhere near as soft & padded as the description & pics lead me to believe. they don't stay in place -- they slip down & i have to keep pulling them up. they're greatly overpriced -- these are $38 but Maggie's Oganics are $21 (less for 3-packs) & they're softer, have much better padding, are warmer & stay in place better. i deleted these socks from my wishlist & won't buy any more of them. if it were possible, i'd give them a negative 3. :(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.
