I bought Shimano SPD-M505 mountain bike pedals and mountain bike shoes at the suggestion of my father. He didn't mention being any easier to get in and out of them as a reason, though. He just said it would be a good idea to get the mountain shoes because they actually have some tread on the bottoms, whereas road bike shoes are smooth. As I am not necessarily interested in speed (road bike shoes are smooth so they have less wind resistance/drag), I agreed. I didn't want to be one of those at the Stop N Go busting their butt on that hard tile floor!
