Birkenstock Arizona Black Leather Sandal Slides Size 37. In excellent used condition as shown. Classic Birkenstock sandals with black straps. Features adjustable buckles. Comfortable brown footbed. Size 37 is a 6/6.5 in birk sizing. I’m a 6.5/7 and this fit really well but I’m selling because I just don’t wear them as much as my clogs.
