I quit riding platform pedals w/ sneakers after too many slips/falls off pedals, especially when either pedals or shoes were damp. Toeclips tore up the front of my shoes quickly. I prefer the double-sided MTB pedals and the MTB shoes (SPD cleats) - love my Keen bike sandals. The MTB shoes are quite comfy to walk in and get good traction both on the pedal (before clipping in) and on pavement/rocks. I really feel more secure when standing on the pedals to climb. I probably get better power transfer with the stiffer sole road bike shoes, but lots of intersections and sections of off-bike walking favor the MTBs.
