The Kilpi AKARO-U socks offer climatic comfort thanks to a knit made of elastane and synthetic fibers, which create air chambers for maximum breathability and at the same time increase the durability of the sock. The wide, flexible ribbing of the upper hem does not press and does not impede blood circulation. The airy, structured zone in the instep area eliminates sweating and fixes the position of the sock.
