Birkenstock Yao light blue suede sandals. The footbeds are worn down so you cannot read the size. I compared them to another pair of Birkenstocks I have in my posh closet to get the accurate sizing. These are an EU size 38 , which is a US 7 - 7 1/2. Comparing them to these other Birkenstocks, they are a narrow width. Some cork cracking as photographed, could be reinforced by a cobbler, but on mine, I just add a little super glue, and that stabilizes them. Silver tone buckles. Priced accordingly with the flaws. I would consider these in fair condition, but they are quality well made shoes so still have plenty of good life in them. These appear to be suede to me.
