Cold feet ruining your winter fun? Not anymore! These heated socks are here to keep your toes toasty, whether you're skiing, ice fishing, camping, or just braving a chilly day. They're powered by a powerful 5000mAh battery that lasts up to 7 hours on a single charge—and with a higher 7.4V voltage, they heat up faster and more efficiently than many other socks. You can choose from four precise temperature settings: 45°C, 55°C, 60°C, or 65°C (indicated by handy colored lights). The socks are unisex and come in sizes M (US 3-8.5) and L (US 7.5-10), with the L size offering extra room in the leg. They’re made with three cozy layers: soft inner mink fleece, safe heating wires in the middle, and a breathable, washable outer layer that holds its shape. No more bulky, uncomfortable thermal wear! These socks are slim, flexible, and perfect for all-day wear. Say goodbye to frozen feet and hello to warm adventures. Your winter just got a whole lot cozier!
