Technically, the straps are called, "clips." More modern retension systems are called "clipless" because they don't use the strap (which, again, is called a "clip.") Instead, the pedal clamps onto a cleat on the bottom of the shoe. There are many kinds of clipless, some easier to get out of than others. I'd say have him try out Speedplay or SPD systems to see if getting in and out is an issue.
