I had ordered a size 9, wish I had ordered a 10. I though I would wear them and strech them, but it is not working well. They hurt a lot across the ball of my feet. My toes don't quite go all the way to the end. I think if they did it would fit just a bit better, which also makes the heel of my foot go just past the end of the shoe. As far as standing on them, it feels ok. It boosts me up and inch, and they are cute, but almost too painful to wear.
