size 37 birkenstocks I don’t know that these are real (reflected in price) or super rare but I’ve had them for years. As cute as they are, my feet don’t love them. I have about 15 pairs of birkenstocks and know them well, so I would genuinely say these are of the same quality and comfort as the real deal even if they aren’t the real deal, and they fool me. Gently worn, you can see some dirt that would likely come off and the bottoms aren’t worn much at all.
