I really liked these shoes when i first got them.  They fit decently (a little tight) and i didn't have any of the trouble the other reviewers had with them staying on my feet.  However, i went to the lake one day and left them sitting by the pool in the sun and they haven't fit right since.  I can still technically get my feet into them, but they are severely uncomfortable.  They create pressure on the tops of my toes and the side of my foot.  It didn't occur to me that sitting in the sun could get them too hot and reshape them but perhaps it should have.  In any case, they are useless to me now.  If that were my only issue i would probably give this shoe 4 stars because they were nice me to begin with. However, the combination of tiny vent holes and a tight fit make for a sweaty foot.  If i got them again i would get a size larger and keep them out of the sun.
