Mine was a learning curve: before clipless every time I stopped I put both feet down. No matter how many times I had "practiced" with my clipless, the first time I went to stop fast I tried to put both feet down again. The last time I fell I was stopped with one foot down. When I unclipped the other foot and put it down the sidewalk was sloped and I didn't know that.......Oops! lol - not really the pedals fault.
