So the consensus seems to be, in terms of efficiency, there is no appreciable difference between platforms and clipless.
But what about soft vs stiffer shoes?
I decided to ditch clipless for my upcoming tour, but now I'm deciding what type of shoes to wear. I want to bring my minimalist runners because they are very light and breathable, but the sole is like a wet noodle. How exactly does flex in the sole decrease efficiency? Is it mitigated by the large contact area of a platform pedal?
