I measured my foot according to the sizing chart.  According to the chart, I ordered the size that was suppost to fit my foot.  I have to return it because it is too small, but find I have to pay 4.95 shipping costs to return them.  I guess that is what I get for trying to buy shoes online.  You should try them on first before buying.  Make very sure the shoe will fit before you order it.  Loved the looks, but doesn't make up for the wrong fit.
