I absolutely love the look of this sandal.  Given the narrow width size, I was hesitant to order these, but the width is fine for my medium size foot.  This is my first pair of Birkenstocks, so I am easing into wearing them, as I'm not sure they will be comfortable for all day wear.  The arch support seems to hit my foot at an odd spot at times, and the rigid sole takes some getting use to.
