DeFeet was born in 1992. The first product was a totally customizable, open mesh weave airflow sock. The world's top endurance athletes took notice immediately. The characteristics of those early designs are evident throughout the DeFeet line, today. From technical synthetic fibers, to wool and wool blends, DeFeet's cycling socks are consistently the most durable and consistent performing options made. Elegant, simple, useful and built to last, here in the United States.
