Coach Black and Silver Studded Sneakers default 8.5 and 8

Elegant black sneakers with silver studs. Features shiny silver toe caps. Stylish and modern design. They have a flaw. I bought them in New York, and the salesperson had me try on sizes 8.5 and 8. I decided to take the 8s. But he made a mistake when packing them and put both the 8s and the 8.5s in my box. It was only when I decided to wear them at home that I noticed his mistake. I've worn them a few times, which is why I'm selling them at a lower price. The left shoe is a size 8.5 and the right shoe is a size 8.
