Always on the look out for interesting, high quality brands we found American Trench and got in a selection from their sock range. The Random Plait Crew Socks are knitted in Iowa at one of the oldest continuous running hosiery factories in the USA, each strand of recycled cotton yarn in our Random Plait Crew is randomly incorporated into the socks based on the machine’s mechanical vibration. As a result, each and every sock—even within pairs—are one-of-a-kind.
