3D Knitting Technology
Socks that adapt to your foot—not the other way around
UYN uses three-dimensional knitting technology in its socks, strategically placing compression zones, padding, and ventilation exactly where your foot really needs them—on the instep, heel, and toe area. This reduces pressure points in tight ski boots and prevents the sock from slipping while walking or skiing. This difference is especially noticeable on multi-day ski tours or long days on the slopes, as your feet get noticeably less tired. At the same time, the reinforced zones are knit so finely that the sock doesn’t add bulk under the ski boot and doesn’t alter the boot’s fit. This ensures plenty of freedom of movement for your toes, even when worn for hours on end, without any pinching or squeezing inside the boot.
Anyone who spends their days in ski boots or on the trail quickly realizes how much a well-fitting sock makes a difference—for example, the UYN Trekking One Merino Men, which was developed specifically for this purpose. For women, there’s also the UYN Trekking 2In Merino Women, a version tailored to the slightly narrower foot shape. If you’d like to see the full selection of sizes and colors, you’ll find them all in the ski socks category at ski-shop.ch.
Merino Wool
Merino Wool: Warm in the Snow, Cool on the Trail
At the heart of every UYN sock is a carefully balanced merino wool blend that naturally regulates temperature—keeping you warm when it’s cold and breathable as your activity level increases. Merino also absorbs significantly more moisture than traditional synthetic fibers without feeling wet or cold, which is a major advantage, especially when skiing in tight, poorly ventilated ski boots. Another plus: Merino fibers are naturally odor-resistant, so the socks still feel fresh even after several days of wear on the mountain. UYN combines the wool with technical fibers for added elasticity and durability, ensuring the socks retain their shape even after many washes.
This material blend is featured, for example, in the UYN Trekking 2In Men, which is designed for longer trekking tours as well as cold days on the slopes. For women who prefer light winter hikes, the UYN Trekking One Merino Woman, with its slightly thinner knit, is a great fit. You can find all of the brand’s models on the UYN brand page at ski-shop.ch.
For every occasion
From a day on the slopes to an autumn hike
Even though UYN is best known for its ski and winter socks, the trekking line covers the entire fall and winter season—from mountain hikes in cool temperatures to a full day of skiing on the slopes. The socks are designed so that you can easily switch between hiking boots and ski boots without compromising on fit or performance. For anyone who relies on both skis and hiking boots in the winter, it’s therefore worth having several pairs on hand. That way, you’ll have the right sock for every activity without having to do extra laundry in between.
A good example of this versatility is the UYN Trekking One Cool, which, thanks to its thinner knit, is comfortable to wear even on milder days. If you’d like to browse the entire collection, you’ll find what you’re looking for in the sports socks category at ski-shop.ch—where all brands, including UYN, are directly compared.
