Birkenstock A 630 Polyurethane professional

Purchased these for my husband but they run big. Never worn. Size 43 and 10.5” long. No box. Here are the website details: The A 630 PU clog covers all bases when it comes to stringent hygiene standards and reliable nonslip properties. Its enclosed design and the nonslip treaded sole offer reliable grip and maximum sure-footedness in kitchens and the food industry. Its oil- and grease-resistant material is also water-resistant, allowing it to be cleaned efficiently and thoroughly. This involves removing the cork-latex footbed and washing the clog at up to 80° Celsius. Both parts of the shoe are suitable for daily disinfection. The anatomically shaped original BIRKENSTOCK footbed protects joints and tendons, and is also washable at up to 30° Celsius. The footbed is available separately and can therefore be replaced if necessary.
