Clinically-Tested Padded Socks For Feet That Hurt

Tough on Their Feet

Active kids are notoriously tough on their shoes and socks—and that means they are also tough on their feet, especially during vigorous activities such as basketball and hiking, and winter sports such as skiing, snowboarding and, well,  just about any other sport you can name. Ordinary kids’ sports or athletic socks aren’t up to the challenge. Your kids need clinically-tested  padded socks that can help protect their feet from impact and blister-causing shear and pressure forces—and from the excessive moisture that is a catalyst for blisters, athlete’s foot and other foot conditions. And they need their padded socks to last, game after game, day after day, month after month—even year after year. Thorlos clinically-tested padded socks (CTPS) do just that!

“I have worn Thorlos for years and love them, but for some reason I was buying ‘regular’ socks for my 8 year old son. He didn't like the socks I was buying and they were falling apart after a few weeks, so I ordered him some Thorlos. HE LOVES THEM. He will not wear any other socks now and they are still in great shape after several weeks of wear (even after wearing outside without shoes...).  I'll be buying him Thorlos from now on...” – Melissa S.

Thorlos Clinically-Tested Padded Kids' Socks

Thorlos clinically-tested padding provides your children’s feet with maximum foot protection. We recommended them for kids who already experience foot pain or to help prevent any foot conditions that might occur during or after participating in their favorite activities. The padding is placed precisely where their feet need 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 promote blister formation. 
  • Toe padding: Protects against banging of the toes in the front of your kids’ shoes, especially in high-impact activities, and sports such as hiking and skiing that may require them to go down hills.

"I used to wear my mom’s, but then she got me my own. They’re great. I got more for Christmas and I even got the snow ones. They are my favorite and most comfortable socks I ever had!!”—Jo Ann C.

For younger kids, Thorlos have three activity-specific designs for kids’ shoe sizes 10 thru 13 and youth sizes up to size 4. After size 4, they move to adult styles. The three activities are:

Kids’ Sport (KAX/KAMX): This is the kids version of our original XJ Running sock. It comes in two lengths (crew and mini-crew) with the classic navy blue pads.

Kids’ Outdoor (KOX): This padded sock is based on our most popular hiking sock, the LTH Light Hiking sock.  Three colors (navy, walnut heather and bubblegum) in crew length.

Kids’ Snow (KS):  This padded sock is based on our original and most protective SKX ski sock. It’s available in four colors (royal, black, blue, and pink) in an over-calf length.

Protection, Durability

Parents tell us that Thorlos CTPS are the most durable socks for active kids, and we know why. Our kids’ outdoor socks, snow socks and sports socks—all with clinically-tested padding—are made with our exclusive THORLON and THORWICK fibers, as well as THOR•WICK® COOL and other synthetic yarns and fiber blends specifically for Thorlos CTPS. They are specially designed for kids who need a padded sock as tough as they are, and offer unprecedented foot protection and resilience compared with ordinary children’s socks.

“These socks are comfortable and durable. My daughter likes them and wears them every day.” — Anna H.

30-Day Brand Promise Guarantee

We promise your kids’ feet will feel better in Thorlos clinically-tested padded kids’ socks or we will refund your money.

“Over 10 years ago, I was at a laundromat doing laundry with my son-in-law when he made an observation: your whole family wears the same kind of socks. Once you feel the warmth and comfort of Thorlos socks, it's hard to wear anything else. And certainly you'd want the best for every member of your family.” – Judith O.

Employee Favorite

“It is great not to have to worry about my child’s feet hurting from uncomfortable socks that rub or cause blisters, or the socks getting holes. While wearing Thorlos KAMX/KAX and KOX, my son does not experience any blisters, and he enjoys the comfort of Thorlos padded socks. Before Thorlos I was constantly having to buy new socks every month or so because the cheaper brands were not durable enough for a young boy’s rigorous activities.” —Tammy Pope, Inventory Planning Coordinator

    My son, only 3 years old, loves wearing these wonderful socks. He prefers thorlos over other brands of socks. I love that these socks don't strangle my sons ankles, they are luxurious and well thought out.

    Even though I am a 59 year old woman, I still have childlike feet. (My shoe size is a children's size 2.) I have struggled to find socks that fit my feet, as sock manufacturers seem to want to make socks fit a lot of sizes when they are dealing with children's shoe sizes. This is understandable since children's feet seem to grow quickly, and what fit two months ago, might be kind of snug today. Size 2 seems to be in the wrong place for comfort. Either the socks are too large and bulk up in my shoes, or they are very tight, causing pain in the tips of my toes. Occasionally I could find socks that fit comfortably, but they seemed to be short-lived and disappeared from the market very quickly. Now, however, I have found Thorlo. I am very happy with these socks and other types I have purchased from Thorlo, as they fit comforably, PLUS they provide padding under my soles, making each step a thoughtless activity, since there is no discomfort or pain involved! Yay, Thorlo! Please don't change the sizing of your kid's socks—at least until after I die! :^)—as they are great for me just the way they are!

    The padding on these socks is great; however the ribbing is shorter than they used to be. I've been wearing these socks for years, and the crew used to go higher up my calf.

    Holes in socks

    08/20/14

    I was recently informed by a thorlos customer service person that you have to, have to being key wear shoes for their warranty to be honored. We purchased 12 pairs for my son a couple months ago and probably half the pairs have holes in them. I called after we spotted the first hole. And after they told me he had to wear shoes, which he's not allowed to in the house so our carpet stays neat, they would replace one pair. Then I got the lecture on they weren't covered. I was also asked if I purchased the right size of sock to make sure his foot fit in properly, which I did. I will not be buying anymore socks because of the amount of money that we spent a couple months ago went down the drain for socks that didn't last him long.

    perfect fit

    I am adult with a small foot so I buy kids' socks. I love the cushioning in these socks and the snog fit. The do not ride down my heel as I play tennis. I wish the sock came up a little higher on my calf but I can live with with that issue. Thorlo ~ keep up the great work!
