These fit as other Birkenstocks I've ordered. I have normal width feet but always order a narrow in Birks. I also order a bigger size than I normally wear. I usually wear a 9.5 but order these in a 41 N (which is a 10 or 10.5).

One note, the leather footbed, vs. the suede footbed, I find they can start to squeak when I walk. Eeek. It doesn't happen often, but it has happened. The other downside is that the black footbed, while stylish, does transfer some to my feet. I'll find my heels are a little black after wearing them for the day. Neither of these issues make me like these less. They are really comfortable, I like the color - pretty unique straps.
