They were legit Birkenstocks. The fit was quite excellent. I own a pair of sandals, chose the exact same size and they fit just perfectly. If you're unsure about size, try some on in a store to get the size you need before buying the pair you want on here. Love these things. They are so supportive. I stood at work for hours in them without pain. Gotta support those arches! One recommendation is to periodically use wax free leather lotion on them every other week or so. Make them last.
