Reposhing this item I purchased from @stylebyserrano. These are in amazing condition- they look new! Unfortunately, I’d say they are closer to a 7 than a 6. Birkenstock says these are 6s, but I wear a 6 in almost every shoe, and a 5.5 in heels. I am swimming in these! I do tend to wear my Birks a little smaller than recommended, though. So, here are the measurements: almost 10” on the bottom of the sole (looks like 9 7/8”). Birko-Flor straps, making them perfect for adventures where they might get a little damp or sweaty. Smoke free home. Questions? Leave a comment below!
