Unisex Thermal Heated Socks (One Size) use a 3.7V 2200mAh lithium-ion battery that provides power to heating wires which are made of carbon fiber and are embedded in the fabric of the socks in such a manner that they are not noticeable and this results in the inside of the sock being the same as the outside in look and feel. Also, they surround the end and top of the toe to cover the whole toes area and not only on the soles and insteps. Those heating elements that generate heat by resistance and warm up the feet are thin and flexible and provide fast warming and even heat distribution. The temperature level is adjustable. They have three heat settings: low, medium, and high. You can change the heat setting by pressing the button on the battery pack. The different heat settings have different colors and temperatures: Low: blue, 35°C (6.5 hours) / Medium: white, 45°C (5.5 hours) / High: red, 55°C (4.5 hours). They are made of cotton and spandex which makes them soft, lightweight, and comfortable. Also, they are breathable and can keep your feet cool and dry, they are easy to wash and durable, beneficial for sensitive skin, and they can retain their shape and provide a snug fit with the help of spandex. 3.7V Heated Socks are ideal for winter outdoor activities such as skiing, hunting, and camping.
