I simply loves these shoes!  I have had the Dansko Professional in a solid black, and decided that I needed another pair for work (I'm a flight attendant) and wanted to try the patent leather.  I ordered the same size, but it is true that they do run a little bigger than the standard professional and most likely it is due to the way the patent is made.  Still, no concerns.  Just something that I noticed.  Order the same size as you would your other Danskos and enjoy!  Glad I bought them.  It's the only shoe that I can honestly wear for those days of being on your feet for over 12 hours!
