Bought these when they were new from the H&M Isabel Marant collaboration.  As you know, these items sold out very quickly.  Black suede, metal "sequins" details on these pumps are so simple, yet elegant.  So worth the money and yes, I paid full price.  These are marked 5.5 inside on the shoe and on the back sole they are marked 36.  I believe I am a true 36 or 6 with an average to slender foot, so these fit perfectly.  You just have to expect that since it's a pointed toe, it won't be as roomy as round toe shoes.  So lovely, worn just once.  Since I didn't wear as much as I hoped, off they go.  Comes with dust bag and price tag.  Please feel free to ask any questions.
