I had been ogling these shoes for quite some time.  Tried them on several times, trying to talk myself out of them, because of the price.  Obviously I didn't succeed. The first time I wore them one of the straps rubbed.  The second time I wore them the problem had disappeared. I have worn them with shorts, skirts and slacks, casual and dressy.  These sandals go everywhere and wherever they go they get complements.  I wear them barefooted and I think that that is the way they were intended.  I wear a size 8 shoe and the 39 fit perfectly.  Naot makes a quality shoe - enjoy!
