I bought these shoes after I purchased a couple other variations on the Frano Sarto pump.  They are very similar in style and run a bit narrow (as do the others).  I normally wear a AA but these B width fit me perfectly.  The only compliant I have about them is that the leather around the toe is somewhat rigid and caused blistering and bleeding the first few days I wore them.  I didn't have that problem with other versions of the pump I bought, so it could have been a problem with this particular pair.  But they are finally wearing in - I just can't wear them for extended periods.
