I have the Gore booties. I can't say how well they work, because I can't close one of them. Seriously, it's like my calf is too big. It's quite strange. I got them on sale last year. DH likes his, though.
I have some mid range insulated booties that have velcro for the closure that work well for road rides. I have been known to use foot warmers at below 42 degrees or so, also. I end up wearing my thin smart wool x country ski socks. I have a few pairs of woolie bullies, but I really have to loosen my shoes.
I also have a cheap pair of PI booties with zippers and velcro for my mtb shoes. They are all ripped up on the bottom, but they do work.
