Birkenstock Boston Felt Gray 36 Size is 23-23.5cm. There is pilling and dirt on the felt. The soles are also worn. There is peeling near the sides of the heels (see photos 9 and 10), so there may be further peeling in the future. It has been repaired once. Please check the photos carefully for details. If you have any concerns, please be sure to comment beforehand. Overall, it has a used feel, but how about it for Birkenstock lovers? It will be shipped without a box, wrapped in packing material. We would appreciate it if you would consider purchasing after fully understanding that it is a used item. We do not accept claims or cancellations after purchase. Thank you for viewing.
