Yao is a comfortable Birkenstock slipper that sits a little tighter on the foot than the classic Madrid. The two adjustable buckles and the fine straps that sit slightly higher on the instep provide extra comfort. The straps in old pink nubuck leather feel very soft; no blisters, redness or irritation! This Birkenstock also comes with the anatomically shaped foot bed.

Birkenstocks have a large fit. You probably require a smaller size than the one you usually take.
