Also, the method of charging is via USB-C. A few were Qi-certified but did not charge my Pixel 5 (Choetech sadly was amongst them). The sole is a little to thick in in the toe area. I have been buying BIRKENSTOCK for 25 years and this product from Amazon Germany is so much better value and cheaper than those via any other Amazon site. and an amazing value for price of shoe. My wife received the shoes today. The door was too thin to use the provided skrews. They?re up on the walls now so I doubt we?ll take them down. This is the 2nd time I ordered these shoes and now after they arrived I tried them on only to find out that they are way too small. Im not sure if you can buy these elsewhere, like a plumbing supply store, or not.
