Picky husband says these are very, very comfortable.  Order a half-size larger and a width wider than the size you normally wear.  That is typical for Nike athletic shoes across the board.  He wears an EE in width and a shoe size of 11.5. I order a 12, EEEE and they fit him comfortably. The photo has the Nike 12 EEEE next to his Propet 11.5 EE snow boots.  You can see the length and width of both shoes are identical
