Who is changing their shoes after the ceremony?

I want to have some comfy shoes to wear at the reception. I was gonna go w/ flip-flops but I just don't see them being good for dancing (I can see myself tripping ..not good! )
I worry that ballet slippers will either be not comfy (I have a pair of black ones that can hurt across my achilles heel area..I guess b/c of the elastic) and will have my dress really dragging...
please show me pics of what you're wearing!! I need something ASAP
