Socks for cross country (XC) or Nordic skiing are an essential matter and vastly underrated when it comes to skiing comfort. Ski socks are a base layer that is next to your skin. They control moisture and keep out the cold. They can prevent the formation of blisters. They can make your ski boots feel too tight or too loose. Skiers will “evaluate” their socks by comfort, fit, and durability. In 2024, the price for a pair of Nordic ski socks ranges from $15-30 per pair.
Peek in my sock drawer and you’ll find more than ten different brands of cross country ski socks (and a bunch of snowboard socks, too). In alphabetical order my collection includes Bridgedale, Darn Tough, Falke, Farm to Feet, Fischer Durazone, Norpen, Point 6, Paka, Swiftwick, and Thorlo. Aficionado, indeed.
The key characteristics of a cross country ski sock (besides what I mentioned above about comfort and fit include materials, sizing, thickness, height, odor resistance, and moisture control. Technology has come a long way and that is why some pairs cost more than $30 these days. Sock technology gives us elasticity for stretching and to avoid bunching, moisture transport to keep the foot dry even though our feet perspire while XC skiing, and to provide cushioning and durability.
Sock fit involves flat seams and avoiding bunching inside the boot, because these issues will lead to foot or toe blisters, which can hurt, and take time to heal which will curtail your skiing. Once the sock is on, I like to pull on the sock toe area to make sure it is a comfortable fit. I also wiggle my toes after I put my foot inside the boot. Does it feel too tight or too loose in your boots? Does it feel comfortable or are there pressure point issues?
Sock sizing is usually offered in size ranges (such as 9-11) for men, women, and kid sizes, so read the label to be certain that you are getting the correct pair of socks.
The anatomical design of a sock is intended to fit snugly around your foot and calf zones without cutting off circulation in the boot. Socks have light, medium, and heavy thicknesses and this will offer some choices with regard to comfort in the corresponding warm-to-cold temperatures. Wear heavy or thick socks when it is very cold (below 20 degrees Fahrenheit, in single digits, or below zero) and wear light socks when it is warmer or in the spring time. The size and cut of the ski boot (width, toe box, in-step, arch) may be significant for sock comfort. If your ski boots are too big or too small, the type of sock that you wear will impact the feel of the boot. Loose ski boots will be more difficult to control and ski boots that are too tight may make your feet uncomfortable or cold because of restricted blood circulation in your feet. It is a good idea when trying on new ski boots to wear the socks that you would wear on the trails when skiing.
Toe Warmers and Liner Socks
Toe warmers are an air-activated stick-on little pad intended to be placed over the sock above or below the toes inside the boots. Open the package and remove the pad’s adhesive cover, and stick them on your socks in the toe area and then slide your foot inside the ski boot. The toe warmers should last about 5 hours but occasionally they do not work after opening the package (and shaking the pad to activate the chemical heating element). I have had many successful experiences will toe warmers in frigid temperatures.
Liner socks are one very thin layer of sock material made of silk or synthetics. The liner will allow moisture transport and prevent rubbing of the ski sock and the foot. I’ve used liner socks with my thinner ski socks for many years. Liners will add thickness to your sock setup but admittedly using liners appears to be a practice used mostly by old time skiers. Most sock manufacturers will claim that liner socks are unnecessary because all of the properties needed for comfort and moisture transport are built into their socks. This is true as many ski socks today use blended materials. For example, my newest pair of Paka ski socks have 30% Alpaca fiber, 7% Tencel, 59% recycled nylon, and 4% Spandex to provide padded cushioning, a tightened compression arch, ventilation and odor resistance.
Water Transport Trick
After I finish skiing, I dry my ski boots by stuffing newspaper or other types of packing paper in my boots. This absorbs the moisture that the ski socks have passed out to the inside of the ski boot. The next morning before I put my boots on, I remove the paper from my ski boots and enjoy dry boots to hit the trails. This practice may be old school, but it works. Boot dryers are a mechanical way to dry your ski boots and there are many different types of contraptions available in this area if you want to pay for it.
Alpine vs Nordic Ski Socks
Most “regular” ski socks for Alpine skiers are almost up to the knee but XC skiers do not need such long socks. The XC ski boot is lower on the leg compared to the Alpine ski boot and the sock length should correspond. Additionally, XC skiers’ feet are very active with every kick and glide, so there are different requirements for the sock compared to Alpine skiing. When purchasing socks for XC skiing, I look specifically for Nordic or Cross Country ski socks rather than “ski socks.”
Foot Odor
Repelling foot odor is a key aspect of ski socks and many labels will claim “odor resistant.” Sock material made from the Merino wool sheep breed are famous for this characteristic. Additionally, when the Merino fiber is knitted rather than woven, it is super soft. This material insulates and it absorbs and releases heat and moisture very well as a breathable fiber. Merino wool also avoids slippage to resist blister formation on your foot. Of course, if your ski boot already smells badly, it may be difficult for the sock to combat foot odor.
Sock Care
Caring for your ski socks is important because salt buildup can occur from perspiration that gets into the ski boot. It is recommended to wash ski socks in cold water with regular detergent and then hang them to let them dry. In other words, do not put your ski socks in the dryer. This will be important to avoid shrinkage of your socks.
That’s the download on everything XC ski hosiery except for answering the question regarding my favorite XC ski socks. I’m constantly changing my sock preference and continue to acquire more different brands. Currently, the newest brands that I’m enjoying for daily skiing include Paka and Falke but the brands that I use the most during the season include the Fischer Durazone and the Norpen brands. When the temperatures get warmer, I use my lighter brands such as Darn Tough and Point 6.
