The Kilpi RACER-U sports knee socks made of a light, breathable knit made of a mixture of merino wool and synthetic fibers are suitable for sports with a high intensity of load, such as skiing, alpine skiing or cross-country skiing. Different types of knitwear are distributed according to functional zones to achieve maximum comfort. The natural property of merino wool is the ability to neutralize sweat, eliminate unpleasant odors and naturally repel dirt. Polyamide fibers increase the sock's tensile strength and resistance to abrasion. Elastane is known to improve elasticity. Reinforced shin zone eliminates pressure marks from ski boots. The plush heel and toe area is abrasion resistant. A structured breathable zone around the instep helps to wick away moisture. The upper hem of the sock is sufficiently flexible, wide and does not press. We offer Kilpi RACER-U knee pads in two color versions.Material composition: 59% wool, 38% polyamide, 3% elastane
