Keep your toes warm and your feet functional, Fieldsheer® heated socks are a savior for those suffering from cold extremities. Featuring a three-blend Odorsheer™ antibacterial construction that resists odors, as well as highly stretchable fabric that wicks moisture to remove sweat from the skin. These heated socks use ultra-thin lithium-ion batteries that power ultra-thin heating elements designed to provide instant heat on demand. The built-in battery compartment maintains a slim profile to stay comfortable under your outerwear and above most boots. Need a heat change? No problem, use the included wireless controller to select up to 3 heat settings and enjoy over 11 hours of heat per charge. Stay warm and comfortable in all weather conditions with Mobile Warming® technology. Standard heated socks are powered by our 3.7-volt rechargeable lithium-ion battery (3.7V 2,200mAh) – Reliable power in a compact housing. The included AC wall charger (3.7V) quickly charges your two batteries so you're ready to go quickly. The 3.7V DC output port is compatible with all our standard heated socks.
