The BIRKENSTOCK Florida is the perfect shoe for those who want to walk all day long. With its triple straps, it promises a secure hold and an extremely comfortable fit. The new Platform Flex outsole features a slightly larger heel for better stability and weight distribution. Thanks to the new design with horizontal grooves in the front, flexibility is improved, and the rolling motion becomes smoother. Modeled after the original made with cork, these sandals use flexible, ultra-lightweight EVA material. This odorless, tested-for-harmful-substances, high-grade synthetic resin absorbs shocks effectively, is water-resistant, and gentle on the skin. They're perfect for the beach, the garden, or the hotel spa. Only tried on indoors. Size 35, I wear 22.5 cm and they fit perfectly.
