Birkenstock developed the Profi Birki to offer perfect grip and sure-footedness in almost any work environment. With its raised heel section and extended front, it encloses the entire foot and promotes a natural rolling motion with every step you take. The nonslip PU sole proves itself to be the ideal solution on smooth floor surfaces in particular. The Profi Birki is a top choice among long-term employees in hospitals, the food industry, and kitchens. Its outstanding hygiene properties likewise attest to this: the oil- and grease-resistant clog is washable at up to 80 Celsius, while the removable PU footbed can be washed at up to 60 Celsius and can also be disinfected. All Profi Birki models are certified in accordance with EN ISO 20347:2012 OB E (SRB category) .
