I started with them about 3 years ago and in spite of about 4 - 5 falls, I'm still happy with them. I like the way my feet and lower leg are relaxed in them. I had one nasty fall early on when a Taxi faked me out with a little lunge. Got arrested when I picked up my bike to throw through his windshield.

A word of caution. Many or most of my sudden totally unanticipated stops, the kind that produce falls, are when I'm coming up behind female runners. For some reason, they will suddenly turn around, change lanes or do something else completely unpredictable. Won't even look. I now often unclip when I come up on them from behind.
