Bought these on another website due to lower pricing.  Got them.  Have 4 other Jessica Simpson booties in size 11 which fit me fine.  These are way too small.  Even though they are marked American size 11, I noticed after I got them that they switched the European sizing number.  It used to be 11 was a size 43 in Europe.  These are a size Europe 41, so that's about an American size 9-1/2 or 10.  No wonder they are too small.  Too bad they don't list the European size in the description along with the American size.
