This sandal is so so so cute.  I am a fan of Onex.  Love the no-slip sole and couldn't wait for these.  I've been a 7.5 all my adult life and imagine with the rest of me my feet grew a size as well.  I've been a comfortable 8, but I had to return the eights as I did not read the reviews that they run super small.  I literally could not get my foot in the 8 past my toes.  The 9 arrived and I a pouring out of the top, back and especially the sides.  I actually had to double check that these were, in fact, the nines; they were.  If you do not have a narrow foot, these are not the sandal for you.  Too bad, love, love, love the look, but it's not meant to be.
