Lite Padded Socks For Feet That Do Not Hurt

Hiking Puts Your Feet at Risk

Whether you’re a “weekend warrior” or long-distance hiker, no matter how acclimated your feet are to the trail, something always can happen that puts your feet at risk for a blister or other injury. Don’t just cover your feet; protect them with Thorlos clinically-tested padded hiking socks. Thorlos padding has been shown in independent research studies to reduce not only blisters, but also foot pain, pressures that can lead to skin abrasions, and moisture (which promotes blister formation and creates an environment for fungal infections). To further reduce moisture, Thorlos are made with THORLON®, a proprietary synthetic fiber that is superior at both moving moisture away from your feet and staying resilient throughout the day, and THOR•WICK®COOL, also known for its excellent moisture-wicking properties.

For Every Terrain

When you hike, your feet are subjected to a repetitive heel-to-toe motion, and that motion often is interrupted by steep ascents, scrambling across rocks and boulders, downhill stretches, and even off-trail excursions (planned or not!) that can involve dramatic changes in terrain. And, of course, depending on the time of year and geographic location, the temperature can range from 100+ degrees to sub-zero.

“After trying a lot of other socks, the only ones that I will buy are Thor-Lon hikers. Wool irritates my feet, and only the Thorlo cushioning keeps me cruising the woods.” Paul S.

Made Specifically for Hiking

To enjoy hiking more and to be able to do it day after day, trip after trip, you need to protect your feet from its rigors with the most protective hiking socks available. The variable-density padding of Thorlos engineered padded socks (thicker in the ball and heel areas and less dense in the arch) follows the anatomical design of your feet. It protects the weight-bearing areas and reduces the chances of chafing, blistering and skin injuries caused by the pressure, impact and shear forces that constantly act on your feet when you’re hiking.

Our padded hiking socks are available in a range of styles that work on all terrains, in all climates and for all intensities—wool blends for warmth and synthetic blends (THORLON, THOR•WICK®COOL) for maximum wicking in summer--as well as multiple weights of padding so you can get just what you need for the specific terrain, weather, and level of hiking you prefer. Our women’s clinically-tested hiking socks also feature elastic around the ankle for added support, a smaller heel pocket and a custom toe box to provide a better fit for a woman’s foot.

"I love to be in the outdoors, so my wife and I have a standing date every Saturday morning to go on a different hike each week. The problem is I'm 59 years old and overweight. So my boots and socks take all the abuse. I always got blisters when I wore cotton athletic socks. Now that I bought a few pairs of Thorlos hiking socks I don't get blisters, so we've been able to go father and on more difficult hikes and really enjoying the outdoors again." Tom S.

“These socks cushion my feet in all the right places. They provide warmth without suffocation. The Thorlon-wool blend eliminates "wool rash" on my ankles. I bought my first hikers in 2007 and in 2010 I ordered more. I won't hike or camp without them. All my Thorlos are still wearing well and they always outlast me on the trail. Great company, great socks!” Mary G.

When properly fitted with your hiking boots or trail shoes, Thorlos clinically-tested padded socks for hiking will protect your feet on any terrain, in any climate.

If you don’t experience pain while hiking or after hiking, and prefer maximum protection and lighter weight, try Thorlos Lite padded socks. They’re available in men’s, women’s and unisex styles in a variety of blended fabrics.

Employee Favorite

“I started backpacking nearly 40 years ago. After a long layoff, I hit the trails again and have been hiking and backpacking for more than seven years now. The KLT gives me the versatility I need for whatever I encounter. It’s protective enough for me to carry up to a 30-pound pack, and warm enough for most weather I encounter 9 or 10 months of the year. The wool content provides excellent insulation, and if I use it with a liner, it’s perfect even for warmer weather. I have experimented with a lot of different styles and combinations with and without liners, and will continue to do so. But so far I have always come back to the KLT.” Rick Mende, Business Development / Product Performance

    These have become my everyday sock


    These socks are the perfect blend of cushion and coolness. They literally hug and massage your feet (as do most Thorlo socks). I wear these in the operating room year round, and would never go back to another sock. The cost is a wash, as these last me 2 to 3 years before I replace them. Best. Socks. Ever.

    ankle problem


    I am happy with the foot part of the socks but the texture of the ankle part of the socks inside my high Salomon trekking boots created a light wound on my inner ankle bones, unfortunately. It seem for people like me -with very narrow, boney feet, there is a need for ankle padded socks with similar weaving like on the soles or heels. Other wise they are comfortable, warm and dry.

    Great quality and comfort, but...


    I love the quality and comfort these socks bring. I do know that I prefer the KLT's which oddly come in men's sizes only. I know I can fit in their small size. I've visited the site to place an order several times. Unfortunately, the price deters me.Thanks Thorlo!

    Good sock...but not for Giants


    Cushioning is great in the footbed area, and across the top of the foot to prevent pressure/hot points. Toe area is roomy and doesn't tuck or wad my toes up. This part of the sock is spot-on, and fits my big dawgs perfectly. Moisture wicking kept my feet pretty dry and comfortable until right at the end of the day - but then, nothing is really comfortable then, so it's not the socks' fault. The tops are another story. Good elasticity keeps the tops up - at the very top too good. Narrow band of elastic draws the diameter of the top down, causing it to cut into the bottom of my calf and across my shin. Cuts off the circulation and causes swelling between the ankle and top of the sock, and makes for an uncomfortable day. If you're going to put some sort enhanced elastic at the top, may I suggest that you do so in a wider band and in a more graduated manner - this will keep you from having a constrictor band that negatively impacts those of us with nerve damage or other issues. Also, may want to consider expanding the diameter of the top in your larger sizes - those of us with very large feet are usually pretty large all over. I spent years playing football, lifting weights, and as a diver, so my legs are commensurately "thicker" from use and development. Old age has added an additional layer, so finding socks big enough has grown from a challenge to an obsession.
