Yes, on the track where you are not constantly starting and stopping. As you roll off on the infield or apron, you tighten the straps just once. Then, as you exit the track, you loosen the straps just once. When riding in urban traffic with lots of starting and stopping, this is too much of a hassle IMO. Sometimes you have to stop suddenly, and don't have time to loosen the straps to remove your foot, which results in a tipover. Anyways, I use clipless on all but one of my FG bikes, which uses wide velcro straps and bmx platform pedals so I can use normal shoes. I don't adjust the velcro straps, just have them loose enough so I can get my shoes in. It's not as secure as clipless, of course, but good enough for normal around town use.
