How to walk in Rolandos and other 4-5" heels?

The Rolandos I ordered turned out to be too big, but I did find them sort of hard to walk in. I debated returning them and not getting another pair but they were just so beautiful I had to try a smaller size. So I'm waiting on that to arrive. When I was wearing the ones that were too big around the house I just would walk slowly.

I read an article once about wearing heels that said something about the shape of a person's foot also makes a difference. I have a high arch so I think that might help with my ability to walk in heels.
