I usually wear the regular width birks, but I decided to try the narrow this time (since my feet are very average width). They fit great, and my husband made the comment that these are way too flattering to be birkenstocks. I have the black, and they'll be fine for semi-dressy occasions. I had worn my last pair for far too long, so putting these on with their fresh arch supports was a surprise. I had forgotten how supportive a new pair can be. Definitely happy with my purchase. Great shoe!
