I ordered the 11M and had to return them.  I ordered the 11W and they are not much wider than the 11M.  I wear between a 10-11 depending on the style of shoe.  I have the Dara II in black that I purchased at an outlet store and I got those in a size 11M and they are tight as well.  For some reason, I thought the Dara III would be cut larger.  Its been confirmed to me that this boot is cut narrow and it does not matter if its a I,II or III.  It looks great but the fit is a mess.
