This is a used item, but I haven't worn it much since I bought it, so it's in very good condition. I don't know the size when I bought it because the size tag is gone, but my feet are 26.5cm and my Nike sneakers are also 26.5cm and fit perfectly. I've included a picture of me wearing the sandals in the last image, so please use it as a reference. Please understand that we do not accept any claims or returns after purchase for used items. Shipping is included, but please let me know before purchasing if you are in Hokkaido, Okinawa, or other remote islands. I will change the shipping method to Yuu Yuu Mercari.
