Personally I haven't actually know first hand of a cruiser crashing due to dragging the pegs, but I wouldn't be surprised that it could happen, provided the pegs are fixed and not hinged as most primary pegs are. I did drag the stock pegs on my GW a few times but the way they fold up and back it was a non-issue, no problemo, and was nothing more noteworthy than my foot on that peg getting vibrated as the peg "feeler" bolthead chattered on the pavement. The first time that happened the pavement was riddled with cracks and somewhat uneven seams and that still didn't cause an issue.
With the CTX I've had it leaned over a bit in sharp turns but have yet to drag pegs with it. There's more clearance than you think. If you put aftermarket pegs on make sure they are hinged the same as the stock pegs and don't hang down lower than stock and you won't have a problem. All bets off if you put on fixed pegs that are not hinged or hang lower than stock. I don't care for floor boards myself but I know many who do like them. Cannot answer for any resulting putting them on a bike like this one.
