What I like best about clips and straps is the smooth quickness pulling away from a dead stop. At traffic lights, the resuming of movement is nearly intuitive. The tab on the back of the pedal is nudged with the toe and the foot slides right in. No wobbles, no second-try stops, just fluid and fast movement. Straps are only as tight as necessary to keep feet in place on the pedal. I have pedals made to lock in with era riding shoes (I have a pair of 80's shoes with cleats) but have never used them beyond a trial ride. When I was a 15yr old hooking up a set of straps the first time on my Motobecane I would reach down and cinch my feet in tight for fast rides.
