Walter,
I do the same thing that you do. Those two pockets of water the jets fins hold come in handy for a boot rinse.
I've never notice a vacuum effect when removing the fins, but jet pockets are sort of rectangular shaped. Since the boot tops are rounded, there's no real vacuum.
I guess a tighter fitting foot pocket, would need the drain holes. I never really thought about that reason before, I sort of figured the holes were a feature of the injection molding process or something.
