The original waterproof sock. The waterproof sock that started it all. Sealskinz designed the Waterproof All Weather Ankle Length Sock to keep you dry and on the move in wet conditions. Wet feet can lead to all sorts of not-so-good things outdoors, including cold and numb feet, blisters, frostbite, and worse. Designed for a variety of temperatures, stay comfortable and warm with the Waterproof All Weather Ankles in rain, snow, and mud, standing in leaky waders, and through stream crossings. Featuring a three-layer bonded construction that combines a 100% waterproof hydrophilic membrane between 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. 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. 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.
