Shoes too big!

You might try an insert. I like the gel ones. Pick them up at Target or Walmart.

You can add an insole which will lift your foot slightly and also use a gel heel pad.

I also recommend the inserts. I bought my wedding shoes from another bride and they are about a half size too big. I added inserts from "Foot Petals" to the heels and the balls of my feet and now they fit perfectly. I like Foot Petals because they have inserts in the shape of hearts and flowers so they look pretty inside your wedding shoes.
