I read that these will crack, I should have listened. They were cracking where your foot flexes after one week, or wearing to work for about 4 days, I'm a nurse. They are very pretty and shiny. If you are willing to take a chance with cracking/splitting, the sizing is as such: if you take a 9 or 9.5 even wide,  order a 9, larger? Order a 10. These do not give quite as much as some other fabrics of the same style or than the sandals. I cannot recommend these though, because of the cracking.
