I purchased a size 37 early in the summer as I am normally a 6.5 U.S.  They were big, but I out inserts in them and made them work.  At the end of the summer I decided to try the 36, as the 37 stretched a little.  The 36 is a much better fit for me.  My toes are close to the end, but overall I would size down with this shoe.  I have some Bernie MeV ballet flats and those are a 37, so truly depends on the shoe!
