Actually, I've been using the clipless sytem for about 2 years. I think I got complacent. One time a dog was chasing me and I got distracted. That was a pretty bad fall. I felt like I had been in a car accident. What was ridiculous was that it was a really small dog. I haven't had any falls this season, but a few times my foot didn't want to come out. The pedals are adjusted pretty loose. I think I get some dirt in the cleat part, or my toes are going numb and I can't feel if I'm getting out correctly. My husband says I don't use the pedals efficiently. It's kind of a new motion for me.
