These are fake Birkenstocks. Please don't waste your money. Birkenstock no longer allows their shoes to be sold on Amazon by 3rd party sellers due to all the counterfeit ones. I wish I had seen this before I purchased. Birkenstock has a list of authorized sellers. If they aren't authorized, they probably aren't real. Not only were mine fake (the glue and writing was a giveaway)....they were already worn! So I received fakes, used Birkenstocks. Gross.
