The Design of Thorlos Padded Running Socks

Insights into the design, development and testing of Thorlos activity-specific, clinically-tested padded running socks from David Varsik, THORLO's senior design engineer.

What Independent Clinical Studies Say About Thorlos

Thorlos padding has been the subject of eight independent clinical research studies that were published in peer-reviewed medical journals. The results showed the proprietary padding reduces foot pain, blisters and other foot conditions, pressures on the foot and moisture.


  • Constructed with THOR•LON® fibers for superior softness, resilience, durability, and moisture-wicking for drier, better feeling feet.
  • Cushioning over the toes to help protect against runner’s toe.
  • Flat knit instep and cushioning in arch for better fit, more support and less pressure on the feet for a more comfortable run.
  • Low profile toe seam won’t rub or irritate the feet.
  • Unique padding specifically engineered for running, clinically shown to reduce blisters, pain, pressures and moisture for maximum protection.

    I felt like I was walking with sweaters shoved into my shoes. Beware! Money back guarantee does NOT include postage or prompt customer service. Save your dough for better products on Amazon where they will actually pay for return postage and give a care if you are a future customer. BOO!

    Too thick for running sock for me.


    Too much sock for me and did not feel I could grip as well. Great sock to use for other things, but not running for me.

    Why these socks are my favorites


    I love these socks because they are thick and soft where they should be for maximum comfort and support. They are substantial and hold up well after washing many times. Best of all, they don't slide down into the heels of my shoes.

    The only ones I buy


    I use these socks for gym workout and tennis. They are the only socks I buy. An added bonus is that makes keeping the sock drawer organized a lot easier too.

    Feels small


    I have other pairs of thorlos that I love but these feel pretty small. My toes feel squished so I have to stretch them some before wearing. Other than that the fabric feels good. I guess I need to get a larger size next time.
