Waterproof Protection from Drips and Downpours

Our original waterproof sock, beefed up for colder and wet weather. The Waterproof Cold Weather Mid Length Socks with Hydrostop are designed to keep you warm, comfortable, and on the move in the chilliest weather conditions. Waterproof, breathable, and very warm, they're an ideal choice when you're outside in the snow, ice, mud or frigid rain.

Cold and wet feet can lead to all sorts of not-so-good things including numbness, blisters, frostbite, and even worse. Our Waterproof Cold Weather Mids with Hydrostop take the worry out of cold outdoor activities and are proven to keep you dry and warm.

Hydrostop: Extra Water Protection to You Keep Going

In serious downpours water can bead up on bare legs and calves and egress into the socks through the top. So we invented Hydrostop, a silicone-like (although it is silicone-free) elastic taping around the inside cuff of the sock. This added protection reduces the chances of water dripping down your leg into your sock. Problem solved.

An Added Layer of Warmth

Designed with warmth in mind these socks are constructed with the finest Merino wool and an added a layer of terry-loop stitching. This loop stitching actually traps heat within the air pockets keeping you warmer when you're in the coldest conditions.

Designed to Keep You Warm and Dry

Our cold weather socks are crafted using a three-layer bonded construction that combines a 100% waterproof hydrophilic membrane with a premium Merino wool interior for warmth and sweat-wicking, and a durable nylon blend exterior with 4-way stretch for great fit and wearability.

Extremely Breathable

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.

Built for comfort and blister prevention

Designed with a seamless construction including hand-linked flat toe seams and the addition of elastic support on the ankle, heel and instep, you won't notice the seams but will definitely notice the extra comfort and fit.

Handmade & Hand Tested

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