I was a little worried that these would not fit correctly based on previous ratings, don't listen, they are fantastic!  I bought a size 10 and I normally wear between a 9 1/2 and 10, they fit a little big so I believe I picked the right size.  They are super comfortable, the wide heel makes them wearable for the whole night.  I danced in them and never experienced any pain or discomfort.
My costume was the talk of the performance and many asked me where I had purchased them.
If you are needing these, I strongly recommend them.  I'm excited about the many costumes I'll be able to put together.
