I switched to clipless years ago, from toe clip equipped pedals. I hated those, kept forgetting
to pull the foot back when dismounting. I found with clipless, that even when I forgot, the
natural tendency to move out wards from the heel, would do the unclip for me.

The last fall I had with clipless was a while ago when I had fitted new cleats, for some reason,
the left was tight the first few times, and it caught me out at a traffic light, embarrassment, but no
injury. I wouldn't ride without them these days, though I am considering Power Straps ( is that the name?)
