I used these for running, but I'm selling them now as I won't be using them anymore. There are some stains, so please check the photos and understand before purchasing. 【Product Details】 - Brand: NIKE - Free 4.0 Flyknit - Size: 25cm - Color: Pink/Orange - Material: Knit - Accessories: None ※ I have cats and dogs. ※ Since there is no box, the item will be shipped in a simple paper bag. Thank you for looking.
