These are so cute!  I read the reviews and some said they run small . I also know that in South and Central America I wear a size 40, so when I saw that the size 9 was a 39 I thought "Oh, no I should order the 10 (40)."  They are quite large on me both in length and and in with. I ordered a 9 today and will see if it fits better. And........... The size 9 fit perfect and I Iove them. I love maps so these are perfect for me. They are super comfortable.  I have only worn them twice so far and both times I got a ton of compliments .
