My Husband uses these for hunting. He says that they keep his feet warm while sitting for a long period of time, They are not hot, just right . But the sizing could be better as he has to push them to the front for his toes, but it does not bother him or feel funny in his boots when walking.
The first time I used the warmers, my feet became Happy Feet! Have not tried them for very cold climate yet...32 degree night only thus far. Will update review after weekend in January in NYC.
I love to snowboard, but my feet start to hurt about 10 minutes in due to the cold. I've been snowboarding for 8 years, and for the first time, my feet don't hurt if I put these warmers in my boots! They work instantaneously and last for my full day on the mountain! WOULD HIGHLY RECOMMEND!
