These shoes are super cute and I love the way they look. I did order a 10 though I normally wear 9 1/2. The size seems fine. One problem, and it is a big one, the bar between the toes is too wide making them quite uncomfortable. There is a round piece of plastic around the material of which the bar is composed. It obviously is meant to be part of the shoe but looks as it it can be cut off. I might try that since the shoes are so cute and I love them otherwise.
Edited to add that I did remove the plastic and the shoes are more comfortable so I would probably give them 4 stars but still be aware that that toe bar is still a bit too wide.
