Clinically-Tested Padded Socks For Feet That Hurt


Lite Padded Socks For Feet That Do Not Hurt

Run Harder, Run Longer 

We created Thorlos clinically-tested padded running socks (CTPS) over 30 years ago—in fact, they were our very first activity-specific padded socks, designed specifically for runners, based on their feedback about what sock characteristics could help them most. These Thorlos are for active runners whose feet hurt during or after a run or who want to help prevent foot conditions in the future. With maximum protection in the ball and heel, and lightweight cushioning in the arch for a better fit, these Thorlos are incredibly comfortable and provide added heel protection in your running shoe.

Made of a proprietary blend of fibers and padding uniquely designed for runners, Thorlos padding:

What’s more, Thorlos maintain their fit, shape and protective function over time, even after repeated washings.

“I finished my first half marathon with zero pain in my toes, no blisters. I was very sore in a lot of areas, but after 13.1 miles, my feet were happy!”  Maggie H.

Right for Every Type of Runner

Why do you run? At Thorlos, we hear great answers to this question. Many of our customers tell us they run simply because they love the sport, or the challenge of completing a marathon, no matter what the distance. Others run because of the health benefits—or because running gives them an opportunity to commune with nature and achieve a feeling of spiritual wellbeing. Still others tell us they enjoy the sense of community among runners, and value the opportunity to participate in an activity that is accessible to their friends and family.

“I have several issues with my feet--flat feet, bunions, sweat (to the point where my regular socks feel wet and I have to change them. These socks allow my feet to feel normal. Thanks for a great product.”

Regardless of why you run, Thorlos are designed to keep running for as long as you like by protecting your feet from blisters and other foot conditions.

Thorlos Clinically-Tested Padded Running Socks

Even if you do not currently have a foot condition or feet that hurt during or after running, Thorlos uniquely designed engineered padding is recommended whenever running creates high foot stress, such as running on difficult terrain, and for frequent or intense participation. Thorlos CTPS increase your running comfort and reduce the chances of many foot problems, so you can run harder, longer and safer--and enjoy running for a lifetime.

Employee Favorite

“I have plantar fasciitis, meniscus problems, and no cartilage in my left knee, but I run in spite of all that. I have to find solutions for my issues that allow me to continue running. It all starts with Thorlos padded socks, plus the right shoes and inserts. My personal favorite is the 84N Runner. It’s the best of both worlds: maximum padding on a lightweight frame.” James Jesserer, Vice President, Sales

    25 years and counting


    I've been running in Thorlos for over 25 years and the J has been part of my wardrobe for most of that time. That should give you an idea of how I feel about these socks.

    Great for Walking


    As a runner who is now mixing more walking into his fitness regimen, I have found these socks to be very comfortable. I admit that the lack of cushion in the narrow band was a little disconcerting at first, but now I love them. After a 4 to 5 mile walk, my feet still feel like they're ready to go for another 4 or 5.

    They are very lightweight and don't bunch up in your shoes. Great for summer. They wash up real easy. Very comfortable.

    They're soft and squishy but WAY too thick for running. Better suited for cold weather only.

    Floating along. I'd take these to walk in Paris and Rome.
