Trail Running Socks

Run the trails in comfort!

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.

“The cushion is great for trail running. Cheaper socks just do not protect the feet on rough dirt trails like Thorlo socks do.”  Ken O.

    No matter what size you get, these slide down your heel. Don't bother.

    Though I have had very good luck with a number of Thorlo socks, and I really appreciate the colors of these "XCCU" socks, they slide down my heels. I've tried multiple pairs in three different sizes, with four different running shoes, and ALL OF THEM slide down my heels! EVERY SINGLE PAIR! I don't know what's wrong with these socks. I don't know if it's an elasticity issue or what, but they just don't work. I wear about a size 10.5 running shoe. I have tried these in the sizes that are marked on the socks as 11, 12, and 13. With most other socks, I've used a slightly small size, so that's why I started with the size 11 ones. Admittedly, Thorlo lists that as a bit small, so I ordered the ones marked size 12, which are supposedly the correct size for my feet. But, no dice. They slid down my heels within minutes. So... I then ordered them in the size that has a 13 stitched into them, above the toes. They're just a bit better, but a bit bulky in my shoes, as they're really otherwise too big for my feet. I just can't win with these. So, now, I have about ten pairs of these and not one of them is really wearable. Maybe your feet/ankles aren't shaped like mine. I weigh 155 lbs am 5', 10" tall and have what I think look like pretty normal men's ankles, and run about 20 miles a week in size 10.5 Mizuno Wave Prophecy or various very squishy Nikes, also at size 10.5. Sadly, these are a complete failure for me. (I'm going to rate Thorlos, in general, higher that I would just for this particular sock, because many of their other socks are quite good. But, this sock would get a zero!)

    trail this!

    I was a little skeptical of these socks, because they were advertised as being "moderate cushion" thickness. I am a true lover of the "thick" socks for running both trail and road. So, the 1st time I wore them was on a long training run, I thought "lets see how good these socks really are"! Well, I ran the 11 miles and my feet did ache as well as my legs and mind, but not from lack of sock support! I really enjoyed these socks, my feet were dry and comfortable, and no difference in how my feet felt then with my "thick" Thorlo socks. I only wish they had more color options....we gals like colorful socks!

    My husband needed some short socks so I ordered these for him. I notice that he chooses these a lot more often than his other brands. So there! : )

    These are the best socks ever for the beating your feet take when playing Pickleball (or tennis). I have been wearing them for several years and will never buy anything else.
