I have to chime in with Leonard here on the Berthet pedals. I also found them far from perfect. I bought a pair for commuting purposes years ago, and used them on both an old UO-8 and a Norman 3 speed for that, as well as on my Trek touring bike for "fun" riding. The problem I found with them was they were just too small and narrow for my size 13 wide feet. It felt like my feet were hanging off the sides, and if I wore tennis shoes, it was even worse, making my foot feel like it was resting on a very small hard object, much like the common complaint about SPDs. I kept them for years, periodically trying them to see if they worked with this shoe or that, or under different conditions. I never did get happy with them, and sold them about a year ago. I think those of us with big feet need bigger platform pedals than those. I keep wanting to try the MKS model that Rivendell carries, but I'm happy with the curent pedals on my bikes right now.
