The current shoe that I have is rigid on the bottom which in a way would be perfect for the eggbeaters, but if I went the route of the eggbeaters I'd rather have a somewhat more flexible sole rather than the hard carbon I have now. Works great on long rides when you don't have to deal with traffic. I guess I'm looking for a good compromise. I don't want too much cushion on the sole since the eggbeaters spindle is where all of your weight will be placed as opposed to being spread out on wider pedals.
