Well, I finally toppled over... but it wasn't in clipless pedals, however I think it was because of clipless pedals.

I was messing around on my fixed bike in my friend's driveway. Trying to do trackstands on the bottom of the pedals (not in the straps)... started to lose balance, but instead of just lifting my foot off, my dumb ass tried to twist my foot out like on my road bike's clipless pedals and my shoe got snagged on the edge of the pedal. I went straight down.. at least I know now that it doesn't hurt too much. I'm most bummed that the brand new bar tape I put on 3 days ago got a tear in it.
