Our Ski Touring No Slide Sock is a warm, synthetic ski mountaineering sock made of a polyester/ polyamide Drytex blend with elastane content for a precise fit. Its lightweight, synthetic fabric supports moisture management during active use in colder temperatures in the mountains when as your core warmth increases, your feet perspire to dissipate the increase in heat. The high-performance technical yarns in these socks allow air to circulate between skin and fabric to draw moisture away and keep your feet fresh, dry and warm. Designed to support a 100% blister-free fit, NanoGLIDE® yarns at the heel minimize friction and prevent hotspots and chafing. Between the sock and footbed of your shoe, the NoSlide zone locks the foot in place for a more secure fit. This sock also has a 3F wrapping construction for additional support and heel stabilization, and side padding at the metatarsal heads.
