BIRKENSTOCK Papillio Black Leather Buckle Wedge Sandal SZ 40 fits a US 9.5

These shoes are SO comfortable. I have 2 pairs that i have worn out & could no longer make out the size. I got these to replace them and they are too big. My feet are 8.5 - 9. Whatever the conversion may say - I would recommend these for people fitting 9 to 9.5. Brand new.
