Our socks are designed in America and made with nearly 70 years of craft and expertise in North Carolina.

Sock Height measurements are from the top of the heel pad to the top of the cuff. Height manufacturing tolerances of .5” in either direction are to be expected.

We embed our proprietary blend of minerals directly into our Circufiber® yarns, making Circulight® IR virtually indestructible. While no socks last forever, Circulight® IR won't wash out or wear out, giving you the same benefits each and every time you wear them.

While just about all socks have some degree of “compression” (they wouldn’t stay on your leg otherwise), not all socks are defined as “compression socks.” Compression socks are specially designed to apply pressure to your lower legs, helping to maintain blood flow and reduce discomfort and swelling. At present, we do not sell socks that would be considered “compression socks,” though our clinically-proven, proprietary infrared technology addresses similar conditions and provides many of the same benefits. Always consult with your medical professional if you have been advised to wear compression socks.

Presently, our socks do not have a non-skid/slip bottom. We will be offering non-skid/slip options in the near future. If you sign up on circufiber.com, you’ll be the first to hear about new products, offers and valuable discounts on Circufiber products.

You do not need a prescription to purchase Circufiber socks. At this time, our socks are not yet covered by insurance, Medicare, Medicaid, FSA/HSA.

Our socks have been clinically proven to increase circulation in the feet and lower legs of people living with diabetes. While we have not studied our socks on people with conditions such as Edema, Charcot foot, etc. we have many customer reviews on circufiber.com that mention benefits for other foot conditions. If you have any questions or concerns about using our products to treat any disease or condition, please consult with your medical professional.
