Ski Sock Foot Protection Needs Assessment

Foot protection is especially important when skiing. Choosing the right protection for your feet requires careful consideration of:

  • Skill level
  • Boot type
  • Boot fit
  • Terrain

At THORLO, we’ve taken all these elements into consideration in designing our five different ski padded sock styles. Why such an extensive line? Basically because the foot is critical in snow sports…it's the "rudder,” and there are a wide variety of skiers looking to get different things out of the sport.

“I like a really thin ski sock that won't bunch up and is easy to get in a boot. These do all that and are warm as well. I now have three pair of these. Have tried TEKO, SmartWool, Spyder socks in the past. Not nearly as good as these.” Scott T.

“I'm certain that when I go to heaven and get to walk on the clouds this is what it is going to feel like. Without a doubt the BEST ski socks I have ever owned. They keep my feet dry, warm, and comfortable the entire day. If you don't own these socks yet, you should.” Trish M.

Rental Boot: Comfort Fit with Clinically-Tested Padding

Thorlos SKX clinically-tested padded ski socks are best for beginners and infrequent skiers who are very likely to be wearing rental boots and need more protection. The SKX has clinically-tested engineered padding in the ball and heel for shear protection and in the shin to protect against shin bite. Together these provide maximum protection for optimum warmth and comfort on easy-to-varied terrain.

“I have worn Thorlo socks since 1991 and had my first pair for over 10 years before they wore out. My feet are never cold and the warmth is maintained for hours on end -- all day long! The SKX socks not only keep my feet warm, my feet do not slide in the boot. You have had a life-long customer since 1991. Well worth the money.” Susan D.

“These socks were great. I usually get cold feet after a few hours of skiing but these kept me toasty all day. The front padding on the shins is awesome. They also fit perfect around the arch so getting my boots on and off without any bunching was really appreciated.” Cheryl L.

Custom Boot: Performance Fit

For more experienced skiers, Thorlos makes three performance-level padded ski socks: SL, SLW and XSKI. These have been designed for the skier who has invested in custom-fitted boots for varied-to-difficult terrain and who needs less protection. These three styles have lower-profile padding in the ball, heel and shin to protect these areas from shear and pressure forces.


The SL and XSKI use a special THORLON® / THORWICK® yarn blend to wick moisture away from your foot, ensuring your foot stays dry and warm.

The SLW features a merino wool/silk blend (64%) for extra warmth and comfort.

All three styles are also suitable for cross country, telemark and ski touring.

“I have had one pair of the Thorlo Ski Socks Thin Cushion for several years and was ecstatic to find them online last month! These are the perfect weight socks for me. I love the "knee-high" length and it STAYS UP all day---no sagging, even after several years. These socks are thin enough to wear with almost anything but they are still warm enough for even the coldest days! I highly recommend them---they're worth every penny!” Gail M.

Technically Advanced Custom-Fitted Boot: Custom Fit

For elite competition skiers, Thorlos makes the S1TOU padded ski sock. It features special flat-knit protection for the skier who wants a padded sock that provides a ‘glove-like’ fit. It’s designed for those who wear technically advanced custom-fitted boots for competition skiing on difficult-to-challenging terrain and do not want any padding/protection in their ski sock.

“These are the best ultra light ski socks made. I would recommend them to anyone who wants a ski sock that gives an incredible connection between foot and boot.” John K.

“My niece is a J2 ski racer. She asked me to order 4 pairs of Thorlo High Performance Ski Socks - Ultra Thin Cushion for her to use with her new custom ski boot. I put in the order that evening on the Thorlo web site. I did not expect the order to arrive for 10 to 14 business days. Surprisingly, the order arrived on my door step in 4 business days. My niece gave a pair for me to try that following weekend. I was amazed that these thin socks could be so warm and comfortable. I love them so much I ordered another 8 pairs for her and me. Great job Thorlos!!!” Peter M.

Feet Stay Warm with THORLON/THORWICK Environmentally-Friendly Yarn

Regardless of your expertise, on the slopes, a dry foot is a warm foot. Thorlos SKX, SL, XSKI and S1TOU are made with a blend of THORLON and THORWICK yarn that wicks moisture away from your feet, keeping them dry and warm.

“These socks kept my feet warm and protected my shins from boot pressure.” Melonia A.

THORWICK yarn is made from 100% recycled polyethylene terephthalate (PET) bottles. It offers environmental benefits including reduced waste sent to landfills as well as reduced energy and carbon dioxide emissions during production. So wearing these styles is not only good for your feet, it’s good for the environment.

30-Day No-Risk Brand Promise

If you don’t agree that with Thorlos clinically-tested padded ski socks your feet feel better than when wearing regular ski socks, we’ll refund your money.

“The SKX is Thorlos most protective ski product, especially for a rental boot. The extra padding provides comfort and the product also wicks moisture, keeping my foot drier and warmer. If my feet hurt or are uncomfortable when I ski, it can ruin my day and take away all the fun.”Kathy Neill, Director Retail Sales Operations

    Too Thick for Skiing

    02/10/16 | By

    I thought I was buying the same socks as the a pair I purchased in a ski store. These socks were significantly thicker and too thick for skiing.

    Great for All Situations Where Warmth and Padding are Needed

    01/28/16 | By

    These are soft and thick. I use them for motocross because of the padding in the foot and shin areas. I think they might be too warm for summer based on the amount of material in them but for now they are fantastic. Don't buy motocross specific socks, those companies don't know how to make socks. Buy Thorlos, they make a great sock that will last years.

    Love the extra height

    01/22/16 | By

    I've purchased and worn Thorlo ski socks for years. While I can't ski these days do to almost constant vertigo, I decided it was time for a new pair and that they would be perfect for snowshoeing! If I need to adjust the bindings on my snowshoes on the go and have to pull up my snow pants, my lower leg will still be protected from the cold with a sock that goes up to the knee.
