Regular Width (, W, Normal) Manufacturer: Birkenstock Material: Birko Flor Footbed: EVA Sole: EVA Made in Germany and send directly from Germany Sandals Birkenstock’s thong sandals are made with the utmost care. We have meticulously tested and adjusted our thong sandal – until it was best suited to the foot’s anatomy. By the way: prolonged wearing of fashion shoes that are too narrow can result in your toes being painfully constricted – Birkenstock’s thong sandal helps return your toes to their natural position. We therefore recommend that you choose the “normal” width when selecting a model. The “narrow” width footbed has been designed specifically for very thin feet. Our two-width system means that you’ll always find the perfect fit. Try it out for yourself!
