Congrats on the ride, but I have to agree with the others, get them feet locked down somehow and it all becomes beautiful.
If you feel that you are thinking circles now, just you wait until you can push and pull those pedals around. Just start off with the straps looseish and make sure you aren't rocking shoes that will catch (chunky sole treads) or are too bulky. Then once you get used to them you can tighten when you feel ready.
