But wait: this goes for pedaling on the ball of the foot, like in toe clips. If you ride unsecured, with the pedal in the arch of your foot, there's probably less flex; fewer joints in the line. Don't know how much a stiff shoe improves power transfer in that case.

Now, shoes.
Racing shoes are rigid, slippery plastic. Riders shopping for them pick them up and test their stiffness (as though it matters) by trying to bend them with their hands. If the shoe is rigid and unyielding, they heave out an "ahhh..." and consider it worthy.
It's a bunch of hooey, though. Your foot doesn't bend when you pedal a bike. It tenses and pretty much stays straight, just as it does when you walk up stairs. "
