Birkenstock Madrid Big Buckle Slide Sandal (Women). Cognac Leather Size 39 EUB / 8-8.5 US These slides have a TON of life left and are in great condition. *Please refer to photographs as the buckle has discolored the leather a bit based on the strap adjustment. When wearing at the place that they have always been adjusted, you do not see the buckle marks. For reference, I have a normal width foot (not narrow - not wide). If you wear them at the same adjustment that I did, the marks are not an issue. These come from my personal closet. All items come from my smoke free home.
