Birkenstock's Arizona sandal comes in the familiar 2-strap, big-buckle slide. This pair is in a gunmetal color called Anthracite, size 39, and is a great summer shoe since it is waterproof and can easily be hosed off. Comfortable and durable. Lightweight slide-on design with adjustable buckled straps. Birkenstock's contoured footbed supports the arches of your foot and cradles your heel for all-day comfort. Material: EVA footbed; EVA outsole Color: Anthracite (gunmetal) Size: 39 Condition: Gently worn. When I was cleaning them to sell, I noticed little holes on one of the top straps that looks suspiciously like little kitty teeth marks. See photos. You don't see the marks as you're wearing the sandals (unless you get close), but I priced them accordingly due to the blemishes! Birkenstock footwear is made in European whole sizes. The style selected is a Birkenstock narrow footbed that will fit most medium feet.
