Pre-loved by someone who wears a size 8.5. Marked size is 39. So, go with your trusted LOUBOUTIN size over my anecdotal info. Well loved!! But, we suited for someone with a wide foot, as they’ve been stretched to fit. :) Perfect for someone who wears a 8.5W (Women’s US) and is open to some project time (I.e a trip to the cobbler would help them shine!) Priced accordingly for being well loved
