Who We Are

Fox River is a leading U.S. manufacturer of outdoor, sport and lifestyle performance socks since 1900. Fox River is privately owned and operates a hosiery mill in Osage, Iowa at the heart of the country. The central location of the mill helps Fox River offer quick, convenient deliveries across the country and around the globe. Fox River’s premium and performance socks are manufactured at its Iowa headquarters by 200 of the friendliest, hard-working folks you’ll ever meet. Fox River socks have been made in the USA since 1900 utilizing US and imported yarns. We're committed to remaining American-made.

Our Commitment

The Fox River brand is known for its commitment to innovative sock construction and continuous attention to trends in the marketplace. Notably, the brand introduced its signature Wick Dry® moisture management technology in 1985 to help keep feet dry and reduce the moisture build-up that can lead to hot spots and blisters. In 2000, Fox River launched the industry’s first women’s specific-fit performance sock line with smaller toe boxes and heel pockets to better fit women’s feet.

Comfortable lightweight socks.

Denis Netto
Best socks ever!

I’ve purchased Fox River and other brand hiking socks for years. Last January I bought Bomba brand and Fox River socks simultaneously. The Bombas wore out at the heals and got thrown out in less than 3 months; very disappointing. The FRs are extremely comfortable, durable, and fit perfectly, and not one bit or wear-and-tear shows (same as the FRs I’ve had for at least two years). After discarding the Bombas, I bought FR socks to replace them. For avid hikers and longer distance walkers, I learned my lesson and will forever stick with Fox River socks.

just right

I've been wearing these in 6" duty boots and on my feet for three hours at a time. They never shift and are as cool as a sock can be in black boots in the summer. Will purchase again!
