The Birkenstock New York is the perfect sandal for kids because its wide straps keep it securely on the foot even during rough-and-tumble play. When play gets heated, the cut-out sections keep things light and airy. The upper is made from the skin-friendly, hard-wearing synthetic material Birko-Flor in a sophisticated nubuck look which boasts a texture and color that could almost be mistaken for real leather.
