I bought these in an 8.5 Navy because they weren't available in a wide width.  I've found with most Clarks Unstructured that I  need a wide width.  They felt a little tight, but I wore them anyhow.  What a mistake.  The short version is that I've ordered them in a size 9 M and hope that size works.  I love the shoe and the color, but not the fit.

I've purchased the 9M and they fit and feel great.
