  • Outer: 90% Nylon, 10% Elastane
  • Membrane: Hydrophilic membrane
  • Inner: 41% Merino wool, 41% Acrylic, 14% Polyester, 2% elastane, 2% Nylon
  • Finer than traditional wool with tiny overlapping scales that case each fibre, these scales are hydrophobic (water repellent). Inside it's a different story, the fibre core is hydrophilic (highly absorbant). Merino is therefore a wicking fibre and can absorb and release 10 times more moisture than synthetics. Each fibre can absorb up to one third of its own weight in moisture without feeling clammy or wet to the touch. In our socks and gloves, the moisture is then wicked through the membrane to keep you feeling warm and dry

Rated 5 out of 5 by from Amazing technology and comfy cozy! Dry, really warm(er than smartwool's expedition sock), waterproof, but good breathability. On first wear they feel neoprene but then mold to the shape of your foot. I wear mine inside just to warm my feet. A 70$ sock!? But definitely worth it! I'll be buying more.

Rated 5 out of 5 by from Amazing! I bought these for my partner as he was off on a motorbike tour across Europe in mid-winter through snow, ice and copious amounts of rain. In his return, I asked if his socks worked. He then proceeded to hand me his dripping wet boots and the boot liners which were also dripping wet. He then took off his Sealskinz and his normal socks and handed then to me. They were absolutely bone dry. He has done many trips like this and he said that he was so totally impressed with his Sealskinz as he didn’t think they would work as the write up said. They absolutely do. Brilliant and yes, pricey but if you’re out in all weathers and all temperatures and want nice dry, warm feet, get these!!!

Rated 5 out of 5 by from Can feel my toes again! My feet run cold. I live in Minnesota. I'm a bicyclist. I want to ride as often as I can, and that means riding during the Winter, and that has been a problem for my feet. I've tried many different combinations (shoes, liners, vapor barrier socks, overshoes of varying ratings) to keep my feet from becoming numb to the point I could not feel my toes, and that's bad. I have wider feet, so that adds to the problem, as footwear (cycling shoes/boots) in wide widths are not super common. I'd nearly given up. Heard about Sealskinz; read a little about their products, and decided to give their Trekking Thick Mid Socks a try. I opted for those specifically because they have the highest temperature rating (4), meaning suitable for cold conditions. I've worn them twice now, in my 45NRTH Wölvhammer boots. Both rides were Winter rides, with temps below 30 degrees F, and one was nearly five hours in the saddle. My feet didn't get numb and I was always able to feel my toes. I know that the Sealskinz Trekking Thick Mid Socks were what made the difference, as I had been on other cold rides with my 45NRTH Wölvhammer boots, but wearing just thick wool hiking socks, and my feet still got numb. I'm pleased with these socks.
