Clinically-Tested Padded Socks For Feet That Hurt

Heavy Gear Means More Pressure on Your Feet

Trekking is tough on your feet. The weight of your pack and the rest of your gear doesn’t just change your center of gravity; it also increases the pressure on your feet by weighing you down from your shoulders to your hips, to your knees, to your ankles—all the way to the soles of your feet. Add to that the rough terrain and the often, cold, wet winter weather and you are likely on the way to foot pain, blisters and other foot conditions. That’s when you know you need Thorlos clinically-tested padded socks (CTPS)—to help protect your feet, keep them warm and dry by wicking moisture, and comfortable in your shoes or boots.

“Love these. I put them on and immediately felt the extra cushioning all around, so much so it felt like my boots were not going to fit. But once on I felt as though my feet were being hugged with a super comfy/warm pillow. I felt like this all day and I had walked in the snow.” Jacqueline S.

How Thorlos Trekking / Treking / Trecking Work

Shoes and boots for this activity typically have stiff shanks (the part of the boot between the midsole and outer sole that supports the arch and helps give structure to the shoes/boot). Most heavy-duty footwear is made for winter weather, and has leather uppers that resist moisture and snow. Thorlos clinically-tested padded trekking socks, in combination with properly fitted shoes or boots, are designed to help buffer your feet from pain, shear/friction forces, pressures and moisture. Our exclusive THORLON®, blended with wool and other thermal fibers, provides maximum insulation and wicking—keeping your feet dry, keeping your feet warm, keeping your feet comfortable. Spandex is used to provide additional support and comfort.

“These socks have heavy cushioning and are durable. They keep my feet dry. Having tried many other types and brands, I have settled on Thorlo TKX.” Paul V.

Clinically-Tested Padding

Thorlos clinically-tested padded socks are recommended if your feet hurt during or after your activity to help prevent any foot conditions. 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: Extra thick cushioning in the ball and heel reduces shock, impact, shear and blisters while on extended hiking trips.

Instep padding: Moderate cushioning protects against boot pressure and allows for a better fit at the arch.

Ventilation panel: Brings wicking to a whole new level, helping to keep feet warm and dry.

“I hiked 45 miles in and out of the Grand Canyon, outlying areas and Sedona trails and vortexes. I have feet issues, wear orthotics, and these Thorlos were the only thing that saved my feet. Everyone else on the trip (eight others) including two experienced guides, had feet issues. I was the only one who walked away, literally with comfortable, pain-free feet. I will only buy Thorlos!” Elaine W.

Because of the demands the terrain and excursion length place on your feet during a typical trip, we recommend that you wear only our clinically-tested padded socks (CTPS), not our Lite Padded Socks (LPS), for this activity.

“I bought two pairs and they are perfect for wearing with my Blunnies. However, I did not anticipate that my girlfriend would love them so much. They seem to keep disappearing so I will need to get some more - in her size so I can get mine back!” Richard W.

Employee Favorite

“Mostly I’m a week-end backpacker but if I have some buddies who want to do a longer trip and my schedule can accommodate it, I’m there. For those longer days and greater distances, I use the TKX. I usually pack a slightly heavier pack (extra food and clothing), and the padding in the TKX helps cushion my feet and seems to help offset the extra weight.” Rick Mende, Business Development / Product Performance

    Almost too thick

    My feet feel protected, but there are some shoes that I can't wear with these as they are sooooo thick.

    Extra comfortable and cushy socks, really thick! Make sure your shoes are not too tight or you won't have room for these fantastic Thorlos.

    Best sock for standing on cold/winter concrete floors all day!!!

    I am on my feet all day long and keeping my feet warm & dry is almost as important as sharp tools when working in the shop during the winter months. I even wear them during the summer, when working, with my sandals for the extra cushioning.

    The One Sock To Rule Them All

    02/06/16 | By

    These are my socks, and have been for decades. Running, hiking, backpacking, riding, every-day go-to-work, and I sleep in them too. I need no other sock!

    For me, there are no other socks to talk about.

    The TKX are the only socks in my sock drawer... and have been for the past 15 years. What more do you need to know. Buy the best, cry once! The care directions are very helpful. The inside out washing and drying part along with fabric softener keeps these alive forever. PS keep your toenails clipped so that the socks don't prematurely wear out as the fabric doesn't like a sharp or rough edge. PS Please bring back the blue color, as they work better with jeans and much of what i have to wear. Thank you.

    The BEST for hiking

    01/06/16 | By

    I hike 30-40 miles a week. These are the best socks available. Be aware you may need a larger shoe because they are so thick.

    Felt great in my hiking boots!

    12/10/15 | By

    I wore a pair (of the 4 I bought) on a 6-mile hike on NC's Mountains to the Sea Trail along the Blue Ridge Parkway, and they were the most comfortable thing I have had on my feet in my boots that I am breaking in for my Appalachian Trail thru-hike this coming year. They performed great, and I plan to use those exclusively on my 2,200-mile hike starting in late March!
