These foot warmers are an excellent solution to keep your feet toasty in shoes or boots for up to four hours. Just unwrap them and give them a good shake to activate with oxygen. The more vigorously you shake, the hotter they get!
Using these foot warmers is super easy. First, take them out of the package. Then, give them a good, hard shake to let oxygen in and start the heating process. Put them in your shoes or boots, and you'll enjoy warm feet for about four hours. Remember, the more you shake them, the warmer they'll be. There's not much maintenance needed. Just keep them in a dry place before use. If you don't use them right away after opening the package, they might start losing their heat - generating ability, so use them as soon as possible after opening.
