Like everyone else said, order a half size smaller than your usual size. I have a wide foot, so I ordered 5E, and my foot went in, easy. The problem I ran into was that while there was plenty of room inside the boot, with my forefoot width, the footbed was too narrow, and the instep of my foot would roll over it and feel like it was hanging over the edge, mostly on the ball of my big toes. There was no flexibility on the outside edge of the shoe so I couldn't center my foot over the sole. This would have fit if I was a true 4E, but I'm in the 5E range. The boots also felt very lightly made, and didn't offer enough support for a man of my weight. I could feel something through the footbed that was part of the outer sole construction, like it was honeycombed inside for cushioning, perhaps. An older pair of Sketchers Work EH I have are still superior.
