Rechargeable Heated Insoles
Sometimes a product that reeks of infomercial cheesiness still deserves a look. These Rechargeable Heated Insoles can keep your feet warm on cold days. Dubbed as “the world’s first wireless rechargeable heated foot insoles,” they actually measure the temperature of your foot and adjust heat accordingly, so you only get added heat when you need it. A lithium-ion battery stores enough power on one charge to last up to 8 hours.
