If you’re an avid outdoorsman then lean closer. Here’s a gift that will save your little tootsies while you’re hiking in the snow or shivering in a tree stand before dawn: Thermacell heated insoles.

These insoles keep your feet warm, not hot, at the ideal temperature range for up to 5 hours at a time. They’re powered by rechargeable built-in lithium ion batteries that can recharge up to 500 times. These heated insoles come with a wireless remote control that come with settings of Medium (100F) and High (111F).

The insoles can be trimmed to fit just about any size of shoe, and they’re water resistant as well.
