I have googled and asked all over, and I will as you, those who have done the whole wedding and are planning just like me

First, I am not a heel person, I used to be, and I still like them, but my feet get sore fast, the front of my foot that takes all the weight, do the foot savers from like Dr scholls inserts, really work?
Additionally, for corsets, how do you measure for them? I have seen a few different options and I would like to order one online and not have to return it because I ordered wrong
