These are Birkenstock Honolulu sandals. I'm selling them because the size didn't fit. Size is 44, color is black. The Birkenstock Honolulu, with its hexagonal pattern, is a sporty thong sandal. It's the perfect pair for those who value functionality and comfort. Inspired by cork sandals, these sandals use EVA, a flexible and ultra-lightweight material. This odorless, pollutant-tested, high-grade synthetic resin absorbs shocks effectively, is water-resistant, and gentle on the skin. They are convenient sandals for the beach, the garden, or the hotel spa.
