if you have not wear a pair of Birkenstocks you may be miss out . I be on my foot a good portion of my work day and they be nice enough for work and comfortable enough to spend the rest of the evening in as well . birkenstock cork shape to you foot so they be not really a flat , they be just comfortable . the Birko-Flor be a great product they have come up with , really soft inside and they wipe right off so they always look great so I prefer that from the suede but this style be one of my favorite . I have over a dozen pair and they keep come up with these adorable new style and great color and print - comfort and style what more could I ask for ? I really love my birk .
