If your wedding shoes do not feel perfect the very second you put them
on do not buy them. It is a long day and you really don’t want to put
slippers or flip flops on do you? Your dress will then be too long and it is
certainly not as elegant.
Make sure they are comfortable and wear them around the house (while you are bride practicing) so you are certain that they will be comfortable on the big day.

P.S. if you have a choice between awesome looking shoes or not as
stylish but real comfortable. Choose comfort. It is rare for anyone 2
see your shoes under your dress… (Except during the Bouquet Garter
segment if you are even doing that).
Comfort comfort comfort…
Did I mention to make sure your shoes are comfortable?
