Sports socks KILPI RACER-U are made of light breathable knitwear from a mixture of merino wool and synthetic fibers. This combination of materials is suitable for high-intensity sports such as skiing or ski touring. Different types of knitwear are arranged according to functional zones to achieve maximum comfort. The natural property of merino wool is that it can neutralize sweat and thus eliminate unpleasant odors and naturally repel dirt. Polyamide fibers increase the tensile strength of the sock and abrasion resistance. The proportion of elastane guarantees sufficient flexibility of the socks. The reinforced shin zone eliminates pressure marks from the ski boots, the plush heel and toe area is abrasion resistant, and the textured, breathable zone around the instep helps wick moisture. The top hem of the sock is flexible enough, wide enough and does not press. Kilpi RACER-U knee socks can be found in two sports colors.Material composition: 55% polyamide, 28% polyester, 12% merino, 4% polyurethane, 1% elastane
