Clinically proven to increase circulation in your feet and lower legs in a trial at Yale School of Medicine.

The FDA has determined that Circufiber® socks are general wellness medical devices and Circufiber® socks have been awarded the APMA Seal of Acceptance.

85% of participants in a nationwide Quality of Life survey cited an improvement in one or more diabetes-related foot conditions after wearing Circufiber® socks for just 2 weeks.

Created with your footcare in mind, Circufiber socks feature our patent pending Infrared (IR) technology which has been clinically proven in a Yale published study to increase circulation in your feet and lower legs.

Our socks are specially engineered to be super comfortable, easy to get on and off, and non-binding around the leg. Additionally, our socks provide light support and padding that has been clinically shown to reduce pain, blisters, moisture and pressures.

How it Works

Designed in partnership with our team of scientists, doctors and engineers, Circufiber socks feature our patent pending CIrculight IR technology to improve circulation in your feet and lower legs.

  • Your body emits heat
  • Circulight® infrared technology absorbs the heat and turns it into infrared light
  • This triggers the natural process of vasodilation and promotes increased circulation.

"This is my 2nd order. So glad to finally find diabetic socks that work for me. Greatly reduced swelling and neuropathy. The crew height works almost as well as the over-the-calf height. Either height can be worn all day. No cutting off circulation at the stocking tops. No more wet hot feet; they breathe very well. They are not cheap, but compared to what I've spent over the years for socks that didn't help they are worth the price."

So glad to finally find diabetic socks that work for me.
Scott D

"These socks are a God Send. Naturally cured my neuropathy by 100% within weeks of using. I have not had any neuropathy symptoms in the last year. I have way less pain in my legs. Just better circulation and mobility overall. These socks have helped me to walk better an I can even go hiking now. Thank you!"

One of the Best Products

"Most times I get socks, they are either too big or too small, never just right. That is not what I found with these socks. They are the perfect fit for my feet. I am a diabetic that also suffers from neuropathy and these socks help to relieve the pain in my feet. I can always tell if I grab a different pair of socks thinking it'll be ok, I always pay the price for doing so."

Best socks I have ever had
Steven P

"I have always been told, if it sounds too good to be true, beware. Not the case with these socks. I am a restaurant manager with neuropathy in my feet, so I'm on them 10+ hours a day, and I finally found a non-drug item that really works. I highly recommend these socks to anyone with similar issues."

Works as Advertised!

"These are undoubtably the best socks ever for my neuropathy. I wear them every where I possibly can. Takes the tingling out of my feet. Highly recommend these socks."

"It was amazing to come home from work and not have swollen ankles and feet."

"I really enjoyed finally having comfortable pairs of socks to wear. It has been a long time since I have felt truly comfortable with socks and also had minimal to sometimes no swelling at all in my feet and ankles!"

"minimal to sometimes no swelling at all in my feet and ankles"
