Two knitted layers neutralize friction and wick away moisture. From Rywan, a specialist in high-tech socks with over 60 years of experience. Ideal for hiking, running, climbing, and skiing. In these 2-layer socks, your feet are optimally protected against blisters. The inner sock is knitted from particularly soft, breathable Coolmax (polyester) and fits like a second skin. The outer sock, made from durable Dryarn microfibers (polypropylene), wicks away moisture and is designed to move against the inner sock. The effect: friction occurs between the sock layers and not between the sock and foot. Your feet stay dry. The patented climate technology works like a pump in the shoe. Four micro-perforated climate zones above and below the foot expel compressed, moisture-laden air with each step, allowing fresh air to flow in. A test according to ISO standard (9237) confirms up to 251% higher breathability compared to socks without Climasock technology. Comfortable, pressure-free, and slip-resistant fit. Permanently shape-stable. The soft, stretchy ribbed cuff is non-slip without constricting, preventing blood congestion and painful pressure. With arch support from an elastic band in the midfoot area, an extra-flat, pressure-free toe seam, and anatomically shaped heel.
