Take a look here: http://www.motorcyclegear.com/street...oots_2013.html. The reviewer claims that the boots by First Gear, TCX, and Alpinestar tend to be wide. He also identifies the brands that tend toward narrow. Was thinking about the First Gear "Kili" boots myself, just for this reason.
I'm about an "E" and TCX is great for me. I have both full leather and mesh Gore Tex ones and can wear them twelve hours a day and still be comfortable.
I wear BMW all around boots - so far they have been excellent. a less expensive really wide pair are Tourmaster Solution 2.0 - I found the all arounds to be more comfortable and liked the zipper/fold on the inside of my calf.
