A fancy wool and polyamide blend of fabrics dials in the excellent fit, feel, and support of the Craft Warm XC Skiing Socks. The title suggests one sport, but really, these can handle most wintertime outdoor activity. Ergonomic left and right construction with elastane ankle and midfoot support contributes to a precise and supportive profile that doesn't bunch or shift during activity. The wool sole includes reinforcement at the heel and toe for added warmth and durability. The socks are available in the color Black only, and in five sizes.
