text: Be aware that the upper straps on many of the Arizona sandals are NOT real leather, they are called Birko-Flor, which is a synthetic with a fuzzy fabric backing.  Amazon does not specifically state Birko-Flor next to each color name. The description at the bottom of the page adds to the confusion because it is the same description for ALL the colors on their website, regardless of the strap material. While a few colors have the word &#34;leather&#34; next to the color name, and some others state Birko-Flor, the MAJORITY of colors say nothing at all. I assumed that if it didn't specifically state Birko-Flor in the color name, it was real leather. Not so! I ordered the Ice Pearl color and it is synthetic. You have no way of knowing this until you get it at home and it states so on the shoe box. Amazon should clearly state which colors are real leather uppers and which are Birko-Flor, so customers know what they will be getting. I am disappointed at Amazon for not being clear in their description,and at The Birkenstock company for compromising the sandal quality by producing them with an inferior synthetic material in the first place. If the rationale was to make them more comfortable by having a soft fabric backing next to the skin, this could still have been achieved with real leather on top and fabric on the back. I was eagerly awaiting these sandals, and now have to return them. At $110, I expect real leather, not &#34;pleather&#34;.
