As old man winter is upon us once more, it is time to find every possible piece of warmth and comfort that is available out there. Especially for those of you who love outdoors or those who have to work long hours out in freezing temperatures. Here is a set of rechargeable foot warmers that offer a convenient remote operation, and will last you at least 2,500 hours of toasty heat to warm cold feet; that is about four winters of heavy use.
They are powered by rechargeable, built-in lithium-ion polymer batteries embedded in the foot warmer insoles. It takes about 4 hours to charge them up and let you use them for 5 hours of continuous use at medium heat setting (100° F). The heat setting could also be adjusted to high (111°F).
ThermaCell Rechargeable Heated Insoles will cost you $69.99. [Buy It]
