Cold feet really takes the fun out of being outside in the winter, be it for skiing or shoveling the walk. Nothing makes you want to get inside faster than having frozen toes. These electronic insoles should keep you slushing along for a lot longer, keeping your feet toasty warm no matter how cold it is outside. They're powered by a small batter that hangs just outside your boot, and you can control the temperature with a wireless remote worn around your neck. Combine this with your iPod jacket and Bluetooth hat and you'll be the biggest geek on the slopes. Although, I'm going to be honest, if you really drop $350 on a pair of heated insoles you need to get your head checked. Ever hear of wool socks? Or heating packs? They don't need batteries and cost less than $5. But hey, do what you gotta do. — Adam Frucci
