Size 6.  I like this shoe EXCEPT the tiny tab at the very top part of the heel strap.  It is so rough and rubs so badly I have to wear bandaids over my heels to stop rubbing that spot on my heel absolutely raw by the end of the day.  Other than THAT, it is a great shoe.  If you have Heels of Steel, you'll enjoy them.  Crocs!  What were you thinking adding that silly tab?
