I have bought size 9 from Asics, Merrells, and others. They have all fit great. These Crocs are labeled size 9, but would fit 10 or 11. There was over an inch from the heel and the strap did nothing to help. I felt like a little kid trying on an adult's shoes. Very disappointing. Now I have to go through the annoyance and time of returning them. No Crocs via Internet for me ever again.
