I am looking into getting clipless pedals for the road bike and maybe eventually the MTB. I have heard brief mention, but not a lot of talk about problems with the spindles on clipless pedals not being large enough to work with big shoes. I wear a size 12 shoe and my feet are wide enough to limit my options with shoes, but not wide enough to require extra width shoes. Will I have a problem with my shoes rubbing against the cranks?

To get a little more specific, I am probably going to get Chromoly Speedplay Zeros. I am in college and money is a concern, but my knees aren't great and I want a reasonable amount of float. Will I have problems with the Speedplays?

As long as I am at it, can someone recommend a pair of road shoes for me? Something that I can get in size 12 that runs a bit wide. My budget for shoes is around $100, but that is a bit flexible (doesnt mean $200+ though).

Thanks.
