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.

Benefits

  • 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.

    Decline in Build Construction and Quality

    By

    I have been buying Thorlos XJ Running Socks for over 20 years, purchasing a dozen at a time. It really pains me to write this review because I used to love my Thorlos XJs and would buy them religiously. But over the last 5 years I have seen a significant decline in the build construction and quality of these socks. Thorlos XJ Running Socks are much thinner than they used to be, with both thinner pads/cushion and thinner elastic tops, and they are much less durable, showing significant wear after just a few washes. For the first time, I have experienced multiple holes both in the toes and in the top sides. The Thorlos XJs are just not what they used to be and no longer worth the premium price they cost. I hope Thorlos will one day restore the XJs to their former build construction and quality, but for now it saddens me to say I will not be buying any more Thorlos and instead be finding less costly, cotton, thick, cushioned athletic socks.

    Thank you, Thorlo, for responding to my comment about making these in black. I am definitely going to buy a bunch of pairs of these socks. Hopefully you are able to ship to military addresses overseas.

    Great Socks for jogging/running

    By

    These socks are just the ticket for protecting toes, heels and the ball of the foot. My feet have been put "through the wringer" over the many years of working out and these socks are so wonderful for the cushion they provide to "beat-up" feet! I cannot go the distance without them on. Great product!

    Greatest Socks for Running

    By

    I have been using these socks for over 2 decades, running cross country and track as well as hiking. They are the best socks ever made for running, and I’ve tried all kinds of brands and types over the years. The only thing I would like to see added is different colors; please, please, please add an at the very least an all black version of this sock (with blue bottoms if you like). Thank you so much, Thorlo!
