the ease of being able to wear any shoe you want. it got to be very annoying having to wear only clipless shoes so i had to go back to straps but went to double straps. i LOVE clipless for the power and control aspect but hate it for its lockdown method. i wasn't used to being so locked in and didn't find it very safe to use in traffic(of course i was using shimano spd's so that could be a factor of it) i may plan on trying to score a used pair of time attacks and see what the rave is about them. overall straps are very practical for daily use
