They are designed to keep your feet warm and have peel off adhesive backing. He put them on top of the sock above the toes. They last for hours.

Someone will remember correctly, but one brand name is something like Grabber My Coal. I always carried these on nordic and back country ski trips in case of emergency, but never really needed them.

Pity is, they expire after a period of time if not used.

Super great way to fight the cold!
