It takes no effort to keep my foot centered no matter how hard I'm pushing. I've been using clipless* for only a couple of weeks, and I'm already completely sold. I just hate stepping off in a construction zone in the current shoes with the big cleats.

* The first pedal attachments were cages and straps. They were called "clips". The ski-type cleat mechanisms were not that, so they were called "clipless". It's confusing as shit.
