A 640 - Polyurethane - Black
The A 640 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 solid steel toe cap protects toes and the front of the foot from impacts of up to 200 joules. 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 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. The A 640 model is certified in accordance with EN ISO 20345:2011 SB E (SRC category).

01 | FIRST LAYER OF JUTE
The first layer of jute forms the foundation of our footbed. It stabilises the natural cork and latex core.
02 | CORK AND LATEX FOOTBED
The cork and latex footbed is the heart of all BIRKENSTOCK shoes. The shock-absorbing and highly flexible cork and latex core supports and relieves pressure on the feet. The natural materials insulate against the heat and cold and create a good foot climate.
03 | SECOND LAYER OF JUTE
The second layer of jute is placed around the sides of the footbed. This increases the flexibility of the footbed and makes it significantly more durable. This layer of thick, absorbent jute helps to regulate moisture.
04 | SUEDE LINING
The suede lining absorbs moisture. This natural property of the high-quality top layer helps to ensure a pleasant foot climate.
