I use Sorel boots like these:

So you're right, I don't need to hike much. I'm more interested in the long-term keeping the vapor out of the felt liners, since that seems to be the big problem for an extended trip. The liners just plain get wet from my perspiration, I believe. Last winter's trip my feet nearly froze due to the moisture.
I think next time I go out, I'll use the cheap bread bags as an experiment. If the felt liners stay dry, then I might invest more $$ in something more substantial.
