Noble Boot Sock Duo — Black + Grey

Built for proper miles, in both colours. One pair in Black, one pair in Grey — our tallest, shin-length alpaca boot sock bundled together for muddy paths and long hikes, so you're covered whatever the weather, or the wardrobe, calls for. What's in this duo 1 pair — Alpaca Boot Sock, Black 1 pair — Alpaca Boot Sock, Grey Save £5 versus buying the two colours separately (£50.00 individually, £45.00 as a duo). Why alpaca? Naturally temperature-regulating — hollow-core fibres trap warmth in the cold and release heat when it's warm. Moisture-wicking — pulls sweat away from the skin to keep feet dry and help prevent blisters on long days. Odour-resistant — naturally antimicrobial, so socks stay fresh even after hours of wear. Hypoallergenic & itch-free — lanolin-free alpaca is kind to sensitive skin. Lightweight warmth — serious insulation without the bulk, even inside a tall walking or work boot.
