Very interesting. I prefer the feel of being clipped in. Maybe I can devise a way to attach the cleat to the bottom of my foot, ha. Pretty hilly around here, so staying in the big ring would be tough. I've long considered doing a (careful) barefoot commute just to experience it at least once. I'll have to temporarily replace the eggbeater pedals with Pyramids or similar. I've gotten questions about the cycling sandals from other cyclists, including a few in passing cars. I wonder what comments/stares riding barefoot on a carbon fiber drop bar road bike in traffic would bring.
