"Remote Controlled ThermoSoles Boot Liners
You all know the feeling. You've just stepped out the door on a winter morning, for a hike or a snowshoe, and your toes are freezing! The thought of tromping through the forest evokes fears of frostbite. Enter the Remote Controlled ThermoSoles Boot Liners. With the click of a button your (fully rechargeable) boot liners can be clicked to high temps. But then you hoof it for a bit and the feeling returns, and soon you're climbing the highest point in your backyard and your feet (and self) are on fire. Don't annoy your partners by constantly changing socks and shoes. Just use your remote control to turn off (or to the low or medium setting) your liners. Instant control over foot warmth. (Hopeully, we'll get these in the hands of our online gear testers soon, for a true test.) ( dead link removed )
