Birkenstock Arizona Birko-Flor Graceful Pearl White Size 37 Beautiful color with rare gold buckles!! I just purchased these in Europe this summer. When I got home and I noticed that there is now a mark on this inside of one shoe. I’ve tried to clean but it seems to be permanent. A friend suggested color painting over it to match but I’m afraid to. It’s not super noticeable when on since it is on the inside of right shoe. Make an offer!
