Super-light, yet also super-cosy, UphillSport 1 Pair Valkee Alpaca Wool Ultrasoft Socks are a wonderfully warm choice for cold feet. Rated as thermal grade 4, these surprisingly fine gauge, soft and breathable socks are alpaca wool-rich, making them a great wool sock choice for anyone allergic to lanolin (which is usually present in other wools) and suitable for sensitive skins. These plain knit alpaca socks, designed and manufactured in Finland to high standards, are a crew length leg, with a gentle, slightly wider fit. UphillSport recommend that because of the high alpaca wool content, that these socks are not best suited to intensive active wear. Because alpaca is a quite fragile fibre, VALKEE Alpaca Wool Socks are better for light wear as non-active, casual relaxation or bed socks.
