So here's the deal. I bought these in size 8.5, excited when they came in 2 days later. Tried them on and ......they were a little too big. My foot slides to the front so there's some space in the heel and side areas. My DH said they looked like I was wearing someone elses shoes. I love, love, love the look of these pumps. I tried putting padding in the front, but my foot still slides forward. Any suggestions on products that can help me with the fit of these beauties? I really don't want to return them, but, I can't keep them if they're unwearable. It'll be like wasted money. Please HELP me!!!
