I have a wide forefoot and a narrow heel and have always worn flats. I am experimenting with heeled booties and fine that my feet slip forward in them and make my forefoot hurt. I was considering using an insert, but what kind? And do they work?

For those interested, the styles that I am trying are the Sam Edelman Petty booties, Munro Robyn and Munro Riley so if you have any style-specific feedback, I appreciate that.
