These are beautiful heels but if you are using these heels for a every day use at work, then these heels might have problems for you. After my 2nd night of wearing them, the back came out and I wasn't able to use them after that. I couldn't get a refund or even an exchange because the seller said there's no refunds after you wear them. I was upset so I figure this might help other people. Make sure you can get your refund or exchange before buying anywhere.
