My adult son says, "Mom, I'm calling about the socks..."

My first-born is not known for "carrying on" about things such as, well, socks. Let me tell you, he carried on about these! It's all about love between his feet and these socks. Made in the USA makes them all that more special. Now am forking over more sock bucks for my hubby and other sons. I hope they last; I can't afford to buy them every other month! Their back story of quality makes me believe that they will.More > < Less


These are thick. Really, really thick.

Clearly very well crafted, extremely warm, extremely comfortable. One thing to keep in mind, though - they are SO thick that you might not be able to fit into your regular shoes while wearing them. They are fine with boots, but I made the mistake of wearing them with sneakers. A half-hour into my day, I was in pain! (Just a heads up... they're great socks, just know they are really, really thick.)More > < Less


Heavy warm socks

11/27/2018 by Baunita

I purchased these as a Christmas gift for my daughter's boyfriend, They are much heavier than I thought, so we will see how he likes them (or not). We live in Georgia, so the winters are not harsh, but get pretty chilly for a few days, so maybe that is when he will pull them out. Great quality - soft and I know they will be warm!More > < Less


I paid how much for 1 pair of socks!?

These are the warmest, thickest, most comfortable socks ever! Not sure it's worth the cost

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.
