From afternoons at the playground to full days at the zoo, the Birkenstock Kids' Rio Sandal doesn’t slip off or hurt your kid’s feet. Two secure buckles made from Birko-Flor at the forefoot and ankle keep the Original Birkenstock footbed firmly attached to their little feet, which means they won’t step on rocks or trip over a loose fit. The footbed is made from cork and latex with comfortable arch support that naturally conforms to their feet so they never want to take them off. This sandal also has a flexible EVA sole that withstands bike rides and hop scotch fun.
