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.

Liners work great

Keep feet warm and dry in snow boots! Great item and received quickly. Will be ordering more for my guys.

Toasty comfort

I didn’t get the speedy deliver we’ve come to take for granted with Amazon, but definitely worth the wait. Comfy fit, easy to wear under my socks, no seams to bother toes—and much warmer feet. Yippee!

Crew liner

Absolutely perfect to add additional insulation to my boot socks for really cold weather. Definitely helped keep my feet warm and dry!

Susan Kerner
Great socks

The socks that we purchased were for our son who has a disability and wears braces on his legs. The socks are light weight and comfortable. We have purchased many pairs of socks from Fox River. Great quality. Customer service great too. Thank you.
