Nice. I recently purchased a used pair of Detto Pietros in my size. Got my first chance to try them this morning. The plastic soles have absolutely nothing to a) keep your foot from slipping when you push off from a start or b) help you get into the toe clips. I do have cleats on them. I might consider a wee bit of a heel and a little bit of rubber up front. I'll continue with the cleats themselves, however. It hasn't taken much time to get reacquainted with them after using various Sampson and Look pedals for 20-30 years.
