I purchased these last year and used them during a half marathon. I used them a few times for practice, but they didn't fit, and I've kept them stored at home since then. There are no noticeable scratches, and the product is in good condition. Because it's an international size, it seems you should choose one size smaller. I bought them at a running shop called "step," so they are not fake. They cost over 20,000 yen when I bought them. Thank you.
