Heated Hunting Boots?
There are a few manufacturers that are now offering hunting boots that have a built-in electrical heating source. If they work as advertised, they could be a really nice option for those who hunt in sub-freezing temps. Models like this Columbia feature a built in wire harness that acutally plugs into the wall and runs off a built in battery. Depending on the heat setting and battery life, Columbia says they will heat for 4-8 hours.

While I think this is really innovative thinking, I will most like wait and see how these boots do in the market. At this point, I prefer a nice thick pair of wool socks and an appropriately insulated pair of hunting boots.
For some people who really embrace technology, these will be a must have. This will be especially true for the people who freeze every year in a deer stand.
