Mobile Warming 3.7V Premium BT Heated Insoles Medium Black

Constructed with durable deodorized polyurethane fabric, our premium heated insoles provide all-day relief in cold weather conditions, whether it's a frozen job site, a day in backcountry powder, an early morning jog, or late fall camping. With up to 7 Hrs of warmth from a single charge and seamless Bluetooth® connectivity powered by our proprietary MW Connect™ app, which you can easily download on the App Store® or Google Play Store®. Our ultra-thin design fits in a variety of footwear, from work boots to running shoes or ski and snowboard boots and the Integrated 3.7V rechargeable lithium-ion battery recharges quickly. Our premium heated insoles can reduce foot numbness, increase overall circulation, and keep you doing what you want or need longer. Don't let cold conditions force you indoors, stay on the slopes and get the job done with Fieldsheer's premium heated insoles. Since 1978 Fieldsheer has been designing and manufacturing rugged, performance-driven gear for avid outdoor enthusiasts, motorcyclists, workers, and more. The powerful Mobile Warming® Technology combined with our durable PU construction will last more than just one winter season, and when you choose Fieldsheer, you know you've chosen the best. The Bluetooth® connectivity lets you easily navigate the 4 heat settings to find the perfect level of comfort. By heating the footbed from below, you reduce contact with cold surfaces, which in turn increases circulation and keeps your core temperature safe. The heat zone is targeted to the largest portion of your foot to ensure even heat distribution. Unlike single-use heat packets, our premium heated insoles offer a permanent solution for those long, cold winters.
