The BIRKENSTOCK Kay is the clog with foldable heel strap, which offers high-quality workmanship and absolute safety in leisure and work. The strap ensures that the foot has a secure hold in the shoe and cannot slip out - even if it gets a little hectic. The super outsole consists of two components: a highly shock-absorbing midsole made of EVA and a non-slip rubber outsole tested according to EN ISO 13287:2012. The outsole is also oil and grease resistant. The Kay model is ideal for everyday use in hospitals, kitchens and catering.
