The BIRKENSTOCK Kay Clog is a true classic that can be worn all year round. It offers all the advantages of BIRKENSTOCK’s classic Tokio and Boston models in one. The upper instep strap can be folded back if required, thus providing additional support as a backstrap. The two part components sole ensures a safe and comfortable stand. It consists of a damping midsole made of EVA and a slip resistant outsole made of real rubber. The upper is made of Birko-Flor® which is a durable wipeable material. This version features Buster the Dog who will bring fun to your work place.
