These women's sock is soft and warm thanks to its unique Acrylic wool & Spandex blend. The wool on the outside and the skin-kind cotton on the inside regulate your body temperature and are guaranteed to be non-irritating to the skin. The perfect fit also guarantees supreme comfort. What's more, reinforced stress zones provide optimum durability. Toe Style : Socks are knitted in toe style which helps in moisture management and prevent blisters by reducing the friction between toes and shoes during activity. Acrylic Wool : Thick Acrylic wool socks are an ideal solution for keeping your feet warm during cold seasons.Durable and comfortable. Extra Heel & Toe Reinforcement : Our socks are enclosed with a reinforced heel & toe with double Polyamide for strength and a non-irritating, smooth toe seam. Comfort Cuff : They feature a soft-top that grips the leg gently to stay up, but not so much that it digs in or leaves tight rings around calves.
