I already owned the exact same pair of these, and they were so comfortable and as attractive as a mary jane sneaker can be.  Sadly, sadly, sadly -- and foolishly -- Vionic discontinued these shoes.  This is the only pair I could find in my size, so I bought them.  I certainly hope Vionic rethinks and reverses its decision to discontinue this shoe.  I want more!  ;-)  FYI, they ran true to size for me, are well cushioned, have good arch support and rigid enough sides of the heels to help prevent pronation or supination.
