I usually wear a size 10 and that's what I bought. However, there is big space at my heel in both shoes. I have a treated bunion on the right foot, and untreated one on the left. With a pad in the ball of the  right shoe, that one's okay. But no matter what I do to the left shoe, it's painful.
They have to go back. It is SO hard to find a basic pump these days. I hope one of my kids becomes a podiatrist ... they'd be RICH in the next 20 years treating all these messed up feet!

This is the second pair of EasyStreet shoes I've tried that I've had to send back because of fit.
