Birkenstock Gizeh Essentials Kids The classic Gizeh is for kids too! Modeled on the cork sandal, it is made from one piece of ultra light and highly flexible molded EVA. This thong sandal is also shock absorbing, skin-friendly, and perfect for the beach, the backyard, or by the pool. Upper/lining/sole: one-piece molded EVA Details: one piece molded EVA, resin buckle, waterproof, washable, shock-absorbent, ultra lightweight, soft thong Heel shape: flat “Made in Germany” Size is 31 (box says “narrow fit”) - I think these run wide in general (they don’t seem very narrow)
