American Trench mil-spec sport sock is the same sock knit for the US military, including the use of anti-microbial silver filament yarn knit into the heel, toe, and sole. Silver is proven to kill bacteria and promote moisture migration and is a game-changing technical addition to this super hard wearing cotton sock.  American Trench went step further and added a compression band on the foot and additional arch support.  Perfect sock for hiking, trail running, biking and any outdoor activity!
