Have you ever wondered where the phrase “getting cold feet” came from? Your circulatory system has the ability to divert warm blood going to your feet and send it to more crucial parts of your body, like the organs, to keep them warm. This happens not just when you’re nervous (hence the phrase), but also when it’s cold outside. That’s why we need foot-warmers, and the Mood foot warmer seems like the perfect product to kill the chill. The Mood by 83Design doesn’t really need a user manual. It comes with heat settings, and all you do is slide your feet into its little cavity and your toes will be all toasty in no time. Mood even comes with a handle, allowing you to carry it from room to room. Just make sure your cat doesn’t make this her permanent sleeping zone! Designer: 83Design Inc.
