Pioneering innovation in waterproof technology, these socks feature a unique hydrophilic membrane that is 100% waterproof while efficiently wicking moisture away from your skin at a molecular level. The three-layer construction ensures warmth, durability, and complete waterproofing. Experience superior comfort with a merino wool lining, providing excellent moisture control, insulation, and a soft feel. Flat toe seams are incorporated to prevent rubbing and enhance comfort. The innovative Hydrostop feature, a silicone-free elastic taping on the inside cuff, acts as a barrier to prevent water from dripping down your leg and into your sock. Zonal elastication offers added support for a secure fit. Please be aware that due to the close fit between the sock cuff and skin, prolonged use may cause minor skin irritation for some individuals. For those experiencing any discomfort, it is recommended to use these Hydrostop socks exclusively for outdoor activities and for limited durations.
