Please see our current selection of Therm-ic boot heaters.
The Therm-ic 1600 with remote and TrimFit
offers the longest battery power of all systems. Up to 29 hours of heat! Better yet, it offers 4-6 hours on the high setting while many systems only offer 4-6 hours on the low setting! No doubt about it, having warm feet on cold days makes your day more enjoyable. And having a remote control makes adjusting the level of temperature to your boots easier. Keep in mind, you have two batteries to adjust. But the remote control adjusts both batteries at the same time. And if you should forget your remote control, you probably will one day, the batteries can still be operated manually.
