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.

Great Socks, Fox

And they last and last

George Read
Best Damn Socks

Great all year long boot or shoe socks. Had a dozen of these for a decade!

Elizabeth Kamler
Love the sizing

I am very happy with my new socks. I can’t remember when I had socks that didn’t scrunch my toes. I wear a size 10-11 in women’s shoes. I have already purchased others! Thanks Fox River!

Lynette Sullivan
Great lightweight sock

My husband wears these for his job in the labor field. He hates "quitters" socks that fall down. These are great because when you put them on you never have to do anything more with them.

Cinda Michels
