This is the second time I've ordered the California Magnesian brand, both times they had to be returned.  I wear an 8.5 Narrow and this shoe ran very, very narrow.  It's a cute style, very light weight and dressy, but unfortunately just too slim.  I would say that an 8.5 Narrow was equivalant to an AAAA shoe.  The Clark sandal I ordered at the same time (8.5 N) ran true to size and fit perfectly.
