NWOT Bestseller Adidas Black Adilette Platform Slides - US 9

Why pay full price from their store? I accidentally bought the wrong size with these Adilette Platform Slides, but I thought I could still wear them. I tried it once. It didn't work. They kept slipping off. I took too long to decide what I was going to do with them. Could not return. They need to go to someone truly a size 9 or UK 8 or European 42. In pristine condition. Will even come in original box. From a pet-free/smoke-free home.
