i second the clipless !!!!!
just went clipless about...hmmm....an hour ago and they're great!!! i easily added about 3mph to my speed without hardly trying!
i was just going in for a bike fit and decided..what the heck, i'm going to go clipless sometime, might as well try them now....anyway, after the bike fit i went outside with the clipless and loved them...i didn't have the same problem other people report...but it may have been because i've been riding with toe straps the last few months and those are far more complicated to get into (tap edge of pedal with toe, flip pedal, slide in ,etc.,) in comparison, the clipless was a breeze....
to get out of them, i just pictured doing a little michael foot spin and, POP you're out...
