These run large. I wear a 7-1/2, so looked at the conversion chart and ordered the 38--which was 2&#34; too long! Exchanged (not as easy as I thought, what with having to mail it back to Germany) for a 37, which is just right. These are also not as comfortable as I thought they would be for walking. I see why most Birks have more than the one strap: so all the pressure for hauling around that heavy footbed is distributed throughout the foot. Still cute in the silver.
