What can I say, but once I turned my husband on to Merrell Mocs he swears by them, has four pairs, and only wishes he could wear them with a suit.  They provide great support for him and he can wear all day and be totally comfortable.  I will suggest one modification if you don't need the little loop pull thing at the back to put them on.  On each of his Merrells, I held the little tab down against the stripe down the back and sewed it flat against the ribbon strip with a couple of stiches on each side.  Otherwise the tab hangs up the trouser leg and pant legs look funny.
