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

    I surely miss the merino wool/silk in crew length. I'm thrilled that you now offer it in micro, but I wish for both. I'm sure it's hard for you to satisfy all the requests!

    Wore them one time and returned all 3 pair I bought


    Very little padding for a Thorlo product. Were so thin in some parts I thought the socks were going to rip apart. Can't compare the the Thorlo golf socks. I am a diabetic with sensitive feet. They were really sore after wearing these socks for a round of golf. Not what I would expect from a Thorlo product. Probably OK for those with normal feet.

    best socks i've ever worn!


    i really like the arch support. never had that in a sock before. padding's great. i thought these were the shorter roll-down socks but the comfort and feel make up for that. i wear these for bicycling and will still get the roll-down socks. again, best pair of socks i've ever worn. thank you, thorlos. i've been buying and wearing thorlos for many years and wear them almost exclusively. i'll agree with another review on here that online ordering is much better than in store. limited quantities and styles... thank you very much. i cannot recommend this product more highly. fantastic!

    So comfortable!


    I love these socks! They are very comfortable and I love the padding at the toes, that's what helped me through my last half marathon, seriously! Now that I've moved to Scotland I am appreciating that they are warm & cozy too :-D

    Helps my feet feel great after a day of running


    On weekends I spend my days refereeing soccer and am either running or standing all day. On a typical weekend I will referee between 4-8 games and spend several hours on my feet. The extra cushioning helps to reduce heel pain and cramping in the feet. Great product!!

    Best socks for Walking and Running!


    The socks gave me the best support for the pounding that my feeds has to endure from the asphalt. I will not wear any other socks from now on!

    Great running sock


    I started wearing a shoe with less toe to heel rise and a thinner sole. I needed thicker socks for longer runs and these are great.

    Best socks EVER!


    Though the initial price per pair may seem high, these socks are absolutely worth it. I had four pairs that lasted for a year! Following the washing/drying instructions helped them survive through high mileage running and multiple races. I now use my "old" running socks as every day socks since purchasing my new pairs. I rarely ever, if ever, have any foot discomfort when running in these socks and I previously suffered from bad plantar fasciitis. BEST SOCKS EVER!!!!! :)

    Extremely Padded Socks


    These socks feel great but are so padded that i cannot wear them. My shoes do not fit with these socks on. I would need 1.5-2 size bigger shoes. Unfortunately i cannot buy all new running shoes.
