I've only worn these a few times, so they're in good condition with no noticeable stains. However, there is a slight difference in height between the left and right shoes. Please check photos 2 and 5. Even after adjusting the shape, the difference remains, so I believe there was an original manufacturing error. I didn't notice it while wearing them, and only realized it when taking the photos. I don't think it affects wear, but please refrain from purchasing if you are concerned. Thank you for looking.
