Agreed, I'm looking for a fairly stiff sole but with wide toebox and comfortable upper with some give to it.
I have used vibram 5 fingers Trek with platform pedals and they are stiff enough for casual riding. For cycling the foot is just the interface to the pedal.
But barefoot shoes really shine for walking, running, climbing and other foot intensive activities. You can actually build muscles and ligaments in your feet.
