Authentic Golden Goose backless sneakers size 37

Size 37 distressed white leather with grey suede toe /tongue and blue sequin star. Worn only a few times! Purchased at the Golden Goose boutique in LA, CA . Comes with the both dust bags and the Golden Goose authentication “passport”. The 37 is a US size 7 and I should have gotten a 38 for me since I’m a 7 1/2. So they do tun true to European sizes and made in Italy. These are made to be “slides” and are backless.
