Just a few minutes ago I posted my solution to a current thread on C&A, "Winter/Rain bootie advise sought":

Another plastic bag goes over the shoes, and if I'm wearing cycling tights, the ankle of the tights is over the second plastic bag. Finally I use a pair of rubber boots, like Totes over the second plastic bag. My current Totes have a couple small holes in them, but the above described system still keeps my feet and shoes free of rainwater. At the end of the ride [of 14 miles or greater] my feet still may be damp from perspiration, but it's hardly noticeable compared to drenching rain and I'm comfortable.
