Birkenstock Gizeh thong sandals in Plum Purple.....size 36, equivalent to US 5/5.5 according to website (it can also fit 6 in my opinion). This pair of casual sandals have gotten a modern update from Birkenstock. The Gizeh casual sandals are a genuine classic with signature support and a refined, minimalist style. Fun and shiny patent Birko-Flora. Original Birkenstock anatomically formed footbed with lining. Patent leather upper with adjustable metal pin buckle. EVA outsole for traction. New without box....never worn.
