Birkenstock A 630 PU Clog, EU 43 but actually UK 9.5-10

As noted on the Birkenstock website - "This item runs large. We recommend choosing one size smaller than your usual size." Unfortunately, I didn't see this until after purchase from a different retailer, for £60. They are indeed one size too large for me so please treat them as Size 10. There are some small imperfections - little bubbles in the surface on one clog - see images. These were there from when I bought them so much be from their manufacture. Material: PU (polyurethane) Footbed lining: suede Removable, anatomically shaped cork-latex footbed, washable at up to 30°C Sole: PU (polyurethane), nonslip, oil- and grease-resistant Certified occupational footwear in accordance with EN ISO 20347:2012 OB E (SRC category) 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. The A 630 model is certified in accordance with EN ISO 20347:2012 OB E (SRC category).
