The Birkenstock Florida Flex Birko-Flor Platform is imported. The classic Birkenstock silhouette takes it up a notch or two— or three—with these Women's Birkenstock Florida Flex Birko-Flor Platform Sandals. Crafted from a synthetic, skin-friendly yet durable Birko-Flor® material, this platform silhouette is equipped with three adjustable metal pin buckle straps and a contoured cork-latex footbed for lasting comfort specific to your foot's natural shape.
