I bought these a month before Covid quarantine occurred. I was taking dance lessons and was so excited to continue progressing. I never wore them until last summer August 2021 when I took one dance class. I realized I had bought the wrong size. These shoes should fit snug! And I am an 8.5 in flats and a borderline 9 in heals. I was worried that because there were heels, I should go for the “bigger” size. This was before I knew anything about dance shoes. I now realized I am a U.S. 8.5. The shoes are like new, there is nothing wrong with them. They were only worn for 1 hour 15 mins then put back in a box in safe storage.
