If you're an avid outdoorsman or woman in Canada, then you know the importance of having quality footwear. With our winter temperatures and the very real threat of frostbite, it's absolutely imperative that your tootsies remain at least moderately warm to stave off the chill of such activities as ice fishing or stand hunting. But oftentimes those hours of immobility can bring a chill to even the most heavily insulated of feet, and for just those times, we cannot recommend ThermaCell's heated insoles enough. Battery-powered and rechargeable, these slip inside your boots in place of the factory insole and provide an average of five hours constant heating time. And since even their medium setting warms them up 100 degrees Fahrenheit (high hits 111!), chances are you'll only need to cycle them occasionally at most, extending the battery life to well beyond a full day. Operated by remote and available with an optional car charger, they've easy to use, and easy to keep charged up too... and at just $135, they're an absolute steal that may seem like a novelty now, but is sure to become indispensable once you use them.
