My guess is that the reduced pedal feel is causing you to depress the accelerator either less, or slower, or both. That in turn causes the perception of reduced engine responsiveness. Now, I'm speculating, obviously. There's no way to know for sure without actually having some instrumented readings on your throttle positions when you're wearing different shoes.
