These sandals looked cute enough in the picture, but they are made oddly.  They are both too small and too large at the same time.
I bought these in size 9.  The criss-crossed straps fit like a 9, but the strap across the toe fits like a 7, and the heel strap fits like a 10.  They are just totally mixed up.  Do not buy these shoes. These would not fit anyone comfortably, they are designed/manufactured incorrectly.
Pass on these and find something else that will be cute AND comfortable.
