The A640 is an 100% washable slip-resistant professional work clog with steel toe that is designed for work environments that require extra protection. The polyurethane shell can be washed up to 149 degrees and the footbed can be washed up to 85 degrees and is removable and replaceable. This professional style does have an all-around roomier fit than our Birkenstock classic clog styles but we recommend ordering your normal Birkenstock size. Offered in classic footbed in Black Polyurethane. Made in Germany.
