Birkenstock’s Best Selling ARIZONA sandal in SOFT FOOTBED in IRON oiled leather size 43 (US 10 for MEN fits like 10.5-11) in the REGULAR footbed width. Oiled Leather upper and Suede Leather footbed. Nice arch support, a toe grip bar along with a cork midsole work together to provide you with a sandal that becomes one with your foot. The suede leather footbed smoothes with wear as the sandal itself begins to bend and flex as it breaks into your unique foot’s wear pattern. Regarding Fit: I find Birkenstock in general fit a bit generous. This sandal is size 43 REGULAR width and seems to usually fit MEN 10.5-11. If your foot is more wide and you are a size 10 then this may fit fine. Note: Oiled Leathers tend to look a bit distressed. Minor marks can usually be rubbed out with your hands. —NEW IN BOX— FREE shipping via USPS.
