I have size 10-10.5 feet with very, very narrow heels (AAAA) and have a ridiculously hard time finding shoes that fit. I would never normally purchase shoes with such high heels, but this one had so many good reviews (and the heel looked narrow) that I decided to give them a try. I got a size 10 first and they pinched my toes and were very painful to walk in. But I ordered the 10.5 and with some extra padding at the ball of the foot, a heel grip in the back, and an inner sole to keep everything in place, they fit perfectly and are actually pretty comfortable. I mean, I can't run in them, but walking is fine and my toes aren't pinching. I know it sounds like a whole lot of modification, but that's pretty normal for me - they don't make 10.5 narrow shoes in most brands. They are very, very pretty too (I got the black/black fabric which is like a lace overlayer with some sparkle)! I haven't decided if they are comfortable enough to warrant buying a second pair, but once I actually test them out of the house I may decide to get them in another color. I didn't give them 5 stars only because I think they should have a little more padding and any kind of arch support would be great.
