Galactically good. The BIRKENSTOCK Rio sandal is the classic kids’ shoe. Designed back in the 1970s, it has been a laid-back summer companion for generations of children ever since. These seemingly enchanted sandals are just the ticket for little pixies. The upper is made of skin-friendly, easy-clean Birko-Flor®. The high-quality material not only boasts an elegant glitter effect, but is covered with a protective layer to make it exceptionally abrasion-resistant and durable.
