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.

    I love these socks- I wished they were a little-less expensive. I would by 20 more, I wear them to work, pleasure and hanging around the house. They go well with all of my outfits, Dansko's, Born's you name it they work well with work boots (Frye). I would prefer my name to appear Bennett, J.

    best socks for summertime


    the socks are light weight and cool, which is what i wanted for a summer sock. My only concern is that they seem to run smaller than the other socks I have ordered, as such I would probably order a larger size. As a diabetic I need less constraint. Other than the stated concern the socks are great, love the color. Once again, I love Thorlo socks.

    Best socks on the planet!


    These socks are amazing. I purchased my first three pairs about 10 years ago from a comfort shoe store. I'd never before in my life spent so much money for socks - but the clerk at the store rated them so highly that I thought I'd give them a try. Ten years later, all I own are Thorlo socks. whether for my business casual attire or my most casual attire. They are so comfortable. And they are so durable that I'm still enjoying socks that I purchased nine and ten years ago! I've had to replace some lately only because I've lost a few in the wash. (Darn it! How does that happen anyway?) Still, these socks are a tremendous value and one of the best things you can possibly do for foot health and comfort.
