First, let me say that I didn't find that the shoe ran small as other reviewers have said.  I normally wear a 6 -6.5 and I had to order the 36 (marked 5.5-6).  My foot slid around a lot in the 37.  I do not find that the shoes are narrow either.  I have a normal to narrowish width foot.  I usually don't have trouble in width unless its a pointy pump, then sometimes.  The shoe is very well made and cute with soft comfy leather and footbed, and I was initially over the moon about them.  However, after standing in them for about 30-45 minutes while making dinner, let me warn you that they are not as comfortable as you first think.  True, they are very light on your feet and easy to walk in, but I think the arch support is seriously lacking or misplaced.  I had foot pain (mostly in the ball of my foot & arch area) for hours after taking them off.  I was suprised because, that kind of pain is something I normally only experience after being on my feet for more like 2-3 hours in heels.  Something is just not right with them.  I do have a normal to high arch, I'm not flat footed.  I think they will be fine for wearing to an office job but do not plan to wear these out shopping when you will be on your feet for a while.
