I wear us size 7. Someone did a review who also wears a 7. I usually wear 38 but she said get a 39 and I did and they fit perfect. So pretty I saw someone wearing them and had to get them. I have problems with shoes that wrap around your feet. I can wear them without the strings, you can also cut them shorter but I tied them in a bow in the back and cut the strings. I am very crafty just saying these shoes work however you want to wear them. In my case they stay on. they are made ok but if you wear them everyday they would quickly wear out. They are so pretty and comfy.
