Balenciaga stud-heel leather loafer, worn once

Balenciaga, Black stud-heel leather loafer, size 39. Worn once!!! These are like new. After I had my daughter, my foot went up a half a size so these are too snug. I bought them last year at Bergdorf Goodman. No box. I might have the shoe bag, but I dont think so. (Have other shoe bags I can include if interested: Tods or Aquazzura)
