Outdoor Trail Running socks

A Sport that’s Tough on Your Feet

Trail running’s popularity is exploding—it’s a great form of exercise and an opportunity to meet personal challenges and surpass personal “bests.” But running up and down trails, pounding the rocks, slogging through dirt and mud, kicking up dust and dealing with the whims of the weather all take a toll on your feet. In fact, the Institute for Preventive Foot Health/NPD 2012 National Foot Health Assessment has shown that after marathoners, trail runners are more likely than any other sport enthusiast to experience foot conditions, especially blisters

“I walk/run on a dirt/gravel road and was looking for a way not to feel all the rocks in the road. These socks are so good at cushioning that I want to wear them all the time on our farm.” Phileta R.

The Right Gear is Key

Staying on your feet and on the trail requires more than good conditioning. It takes gear that’s comfortable, protects your feet and won’t let you down. Painful feet or a blister will slow you down and take a lot of the joy out of your excursion. The right shoes are important, and many manufacturers now offer a variety of all-terrain shoes to choose from. But shoes are only part of the story for off-road running. The right padded socks are also critical—and here you have only one choice if you want the best possible foot protection and comfort: Thorlos clinically-tested (CTPS) trail running socks. They will protect your feet inside your running shoe and out—the top of the padded sock has a special, one and a half -inch, snug-fit ribbed top to keep dirt and debris from entering the padded sock as you run.

“I've run thousands of miles with these trail running socks, and have tried numerous other types of socks made for trail running; these are hands down the best. The moderate cushion (medium thickness) is perfect for all conditions.” Todd S.

How Thorlos Help

Thorlos clinically-tested padding provides your feet with maximum protection. It helps reduce impact from rocks, dirt and other trail debris, and the shear forces that can lead to blisters and other injuries to the skin and soft tissues of your feet during a trail run. Made of made with our exclusive THORLON yarn and THOR•WICK® COOL fiber, Thorlos also wicks moisture away better, further protecting against blisters and other foot conditions that could interfere with your comfort and enjoyment.

“Used these with new hiking boots in August. No blisters!” Linda J.

Clinically-Tested Padding

Thorlos clinically-tested padded trail running socks are recommended if you experience foot pain or want to help prevent any foot conditions during or after running. The padding is placed precisely where your foot needs protection, and has been clinically shown to reduce blisters, pain, pressures and moisture:

Ball and heel padding: Protects the ball of the foot from the shearing and impact forces that occur while running on rough terrain. 

Toe padding: Protects against banging of the toes in the front of your trail running shoe when you’re going downhill.

“They are extremely comfortable and provide the necessary support in all of the right spots of your feet. Amazing is all I can say and is the reason I bought more and will continue to buy more as long as Thorlo continues to offer them.” Eric P.

    Good Gym Socks

    04/24/16 | By

    I got these because I wanted some thinner gym socks than my current ones, and these were an awesome choice. Padding in the ball of the heel and the toes, I don't tend to run, but for a ten minute warm up jog, they did amazing in that department too, not just for weight lifting. It says it's not recommended to wear these if you currently use the medium to heavily padded socks from Thorlo, which, I wear the medium padding for my work crew socks, but I haven't noticed any bad side effect. Nonetheless, these are amazing all around gym socks. I would totally get another pair if I needed one.

    Fantastic Running Socks!

    I have recently resumed running after a bout of cancer last year and these socks are wonderful! They have enough cushion to absorb some of the pounding, but not too much to make then feel squishy or soft. Fantastic!

    Most lightweight (decent padding though) and snug out of all the Thorlos varieties I've tried.

    Socks save the bottom of my feet. They do not make my shoes tight when wearing.

    These are probably my favorite socks and I have tried smart wool, darn tough, and several other $15/sock brands. They stay put and are snug. A little extra padding but not thick.

    I don't exercise or walk my usual 3-5 miles without my Thorlo socks! I have them in all colors and have also given them to friends as gifts. Thank you!
