I've googled "cycling booties" and found a few links to shoe covers for clipless shoes, but I'd like to knwo if any of you ride them, how they are to walk on, if they get destroyed by walking on, if they are a pain to remove on the side of a curb when you get to work, etc. I'm looking to keep my feet warm while commuting, running errands, barhopping, etc. If you know a good place to get some, please post links as well.
