Grabber MyCoal Toe Warmers

 

These toe warmers are thin and are made to stick to the underside of your sock in the toe region while wearing boots. I also use them on the outside of my sock while in my sleeping bag on nights when it's especially cold! They heat up quickly when exposed to air and they last for about 6 hours. You can usually get a discount on them when buying in quantity. They're self-stick, odorless, non-toxic, bio-degradable, and disposable.
