We took our original waterproof socks and beefed them up to help you take on the coldest and wettest weather. Cold and wet feet can lead to all sorts of not-so-good things outdoors, including numbness, blisters, frostbite, and worse. Our Waterproof Extreme Cold Weather Mids will keep you dry and warm during frigid stream crossings, on blustery cold and rainy days, through icy terrain and deep snow, and even standing in cold leaky waders. With this kind of warm and waterproof protection, you’ll wish you had them sooner -- trust us.

Sealskinz Extreme Cold Weather socks are designed warmth in mind. Using the finest Merino wool, we also add a layer of terry-loop knitting and added padding at the ankle. This loop knitting actually traps heat within the air pockets keeping you warmer when you're in the most extreme weather conditions.

Particularly noteworthy is the unmatched breathability of the hydrophilic waterproof membrane to release perspiration steam and warm air from inside the sock. This creates a high level of comfort for the wearer, even while performing strenuous and aerobic activities, while also preventing rain, mud, and sand from getting inside the sock.

Exclusively handmade in the UK to our unrelenting standards and attention to detail, every single sock is hand-tested for waterproofness.
