I normally wear a size 9 without any issues.  However, these shoes came and did not even fit on my foot.  They are shorter and more narrow than standard sizing (9 US or 39 in EU).  I am returning them and have to pay the return shipping myself since it was not Amazon's error.  What started out as a beautiful pair of shoes at a great value ended up with me having no shoes for the event that I was planning to wear them to and paying the shipping to send them back.  Be very careful if you order these shoes to order bigger than you think you need!  It would be difficult to estimate what that size might be as they appear to run so small and narrow.
