Mule ~ Black Calf Leather Size:42 Can be fitted with opticalOur mules are an in house design that is manufactured for us in Portugal using vegetable tanned calf leathers that will age beautifully over time. The uppers are crafted of a luxe Italian cowhide that has a supple hand with a waxy finish. For extra traction, the mules are built on a cork footbed atop a Vibram mini ripple sole. The upper will stretch and mold to your foot as it breaks in. SIZING: We recommend taking your usual Birkenstock Boston size,
