Hello, I am selling my Dior B25 Slip on Sneakers. They have never been worn. The size is 9.5 US size / 42.5 euro size. The asking price is $600 (retail 750 euros). They are sold out everywhere. They are not even available on the dior website anywhere. These are very exclusive shoes. They’re in new condition. I’ve never worn them.
