The Kilpi RACER-U sports knee-high socks are made of a lightweight, breathable knit made of a mixture of merino wool and synthetic fibers and are suitable for sports with high intensity loads, such as skiing, ski mountaineering or cross-country skiing. Different types of knitwear are arranged 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 fibres increase the sock's tensile strength and abrasion resistance. Elastane, as it is known, improves elasticity. The reinforced shin zone eliminates pressure points from ski boots. The plush heel and toe area is resistant to abrasion. A structured, breathable zone around the instep helps wick away moisture. The upper part of the sock is sufficiently flexible, wide and does not press. We offer the KilpiRACER-U knee-high socks in two colours. Colour: Black, grey, turquoise Sport type: winter Material: 56% Merino wool, 41% polyamide, 3% elastane
