I'm a bit surprised than not that many prople used clipped, slotted cleat cycling shoes with their quill type pedals. I would think that using anything else could result in bad hot spots and pressure points because of the thin pedal cage against the bottoms of regular shoes.
People seem to be too worried about possibly not getting their feet off the pedals when they have to, but it's really easy to release the toe strap buckles with a quick flip of the wrist which becomes instinctive when stopping.
I remeber that it only took me one ride to get used to them.
