Clinically-Tested Padded Socks For Feet That Hurt

Lite Padded Socks For Feet That Do Not Hurt

Stay Fit with Thorlos

What do you do to stay fit? Whether it’s weight training, cross training, Zumba® or other group fitness or conditioning classes, the padding in Thorlos clinically-tested padded fitness socks will help protect your feet from blisters, pain and soreness, as well as the pressures and moisture that set the stage for other serious foot conditions.

“These socks are comfortable for all activities. They keep my feet from sweating, are easy to maintain, and worth the cost.” Dane L.

Available in men’s and women’s styles, these engineered padded socks are specially designed to accommodate the differences between men and women’s feet so that both are well protected and comfortable. Research has shown differences with respect to such characteristics as ankle circumference, circumference of the ball of the foot (greater in men) and circumference of the instep (greater in men). We take these and other differences into account when designing these activity-specific padded socks.

“I like the wonderful soft material and the cushiony feel of these socks while I work out at the gym.” Richard W.

When your feet feel better, your workouts will be better and you’ll reap more benefits from engaging regularly in the fitness activities you love.

Thorlos Fitness Socks—Like No Other Activity-Specific Socks

Spandex around the arch of the foot—that’s the defining difference between Thorlos foot protection for fitness and Thorlos other activity-specific padded socks. That band of spandex provides support and stability—extra protection during the twisting and lateral movements that are part of most aerobic dance and other group fitness classes. Add that to moderate cushioning in the heel and thick cushioning in the ball of the foot for maximum shear/friction, impact and shock absorption—and exclusive THORLON® fiber that rapidly wicks moisture—and you have a winning combination for all of your fitness activities. These padded socks are especially beneficial if you have narrow feet—they stay in place and don’t twist around during those “cool moves.”

Two Types of Foot Protection

Thorlos clinically-tested padded fitness socks are for you if you cross train by engaging in various sports and activities, but have experienced foot pain, discomfort or injury—or if you want to do all you can to avoid foot problems in the future. If you participate in high-intensity aerobics or other fitness activities that create high foot stress, you’ll want to wear these comfortable yet resilient and long-lasting Thorlos.

For maximum protection: Men’s XT and Women’s AX, ARX,AMX—all made with THORLON®, THORLO’s patented, moisture-wicking fabric.

“No other sock fits, wears and holds up as well as these do. Do not even try any other sock.” Polly P.

    They got it right!


    Great fit, padding where needed. You know how some of these low cut socks slide around your foot or slip down--not these. They stay put. My feet are wide--4E--so I was concerned on fit; they are snug--not tight at all. After a month, they seem to be durable as well.

    XCCU uncomfortable


    They are uncomfortable on my feet. Where the padding stops on the underside of my foot (which I'm flatfooted) is causing discomfort.

    Too wide at the toe seam


    I've worn Thorlos for a long time but had given them up when the no-show style took over and I looked dorky in my white mini-crews. I had been wearing some regular thin fitness socks but saw these and thought I'd give them a try. The toe seam is too wide, too stiff, and too bulky. When I wore them they made my little toe bone sore from pushing up against the shoe. I have narrow feet and these just didn't conform well to my foot there but made a lump. I was happy to be able to take them back to the store. If it wasn't that they didn't fit I bet they would have been great as Thorlos usually are.

    Awesome forefoot padding


    These are the only athletic socks I wear! I had surgery on a Morton's neroma years ago but pain persists and the awesome forefoot padding cushions and protects that compromised area without crowding my shoes.

    Best Socks EVER!


    Love these socks. I wear them to run. I wear them to walk. I wear them to work. I have juvenile diabetes and have always been particular about the socks I wear. I have 10 pairs of these now and wear them daily.

    Great overall socks


    I like these socks, much better than cheaper brands. Still I have problems with my feet, very sensitive but at least and improvement over other socks
