The Gizeh EVA Women's features a single toe post strap that fits between the toes, providing a secure and comfortable fit. The sandal is crafted from EVA (Ethylene Vinyl Acetate), a soft, lightweight, and waterproof material that is perfect for summer activities, beach outings, and casual wear. The EVA material offers the same comfortable feel as Birkenstock's traditional cork footbed but in a more flexible and easy-to-maintain design.
