Comfortable and versatile! The clogs Kay from BIRKENSTOCK adapt to all styles and provide extra support with the heel strap if needed - ensuring a good fit, even during more intense activities. The upper is made from Birko-Flor®, a hypoallergenic and durable synthetic material in a nubuck style: this results in a texture and colour that are very similar to genuine leather. These BIRKENSTOCK Kay Clogs combine stylish mocha brown nubuck with essential comfort features. The adjustable heel strap ensures a secure fit, while the anatomically shaped footbed provides growing feet with perfect support for daily adventures.
