Eggbeaters

The foot retention is not very tight. But they're great for commuting/ winter riding. I have quattros on the fixed, candys on the SS MTB, and eggbeaters on the commuter. I just get on with the mechanism.

Same, I use them on my road bikes and my track bike, never had an accidental unclip, but they are very very floaty (half the reason I like them, had time attacks for a year and found them too hard to clip in/out of).
