I'll be working outside again this winter so I started doing my annual web search for warm clothing. I came across this little gem. Foot warmers with a remote control. The remote has a ten "foot" range. If my hand gets 10 feet away from my foot I'll be needing some medical assistance!

How do you keep warm? Last year I bought those packets called Hotties where you shake them and stick them in your gloves and boots. Layering clothing helps but I find that the outer layer needs to be water proof because once you get wet your screwed. The boots I am picking up next week cost over 200 dollars. Living in southern On. isn't so bad, but I often travel north for my job.
