the first time i rode clipless i tipped over while trying to unclip in front of a hot girl too. unexpectedly she ran right over to see if i was ok. best accident ever.

the only problem I had when switching to clipless (doms/shimano 520's) was this instense pain after doing a 70 mile ride. I must not have had my cleats set up right. I have unclipped a few times when taking off at lights. Maybe my shoes aren't tight enough, because I feel my foot lifting up from the insole a lot.
