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). UK Size: 7.5. EU Size: 41
