I don't see the harm in sweating into wool. It won't make you cold. If you're too hot, it's a problem, but you weren't, were you?
If your feet were cold, you have more research to do. It could get worse than just cold. It could get painful, and you could even get frostbite.
Where in Ontario are you?
