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.

Warm feet

I work and workout outdoors. Keeping my feet warm and dry is always an issue. These socks fit nicely and work great.

So Far So Good

I've been using these as sock liners underneath my Darn Toughs to prevent blisters in my calf-height rubber work boots. After a month or two of a 12-hr shift once a week they show a little wear and stretching in the heal but they still fit comfortably and I haven't had a blister since. I'll probably be purchasing another pair or two as we get closer to summer.
