text: Finding wide hiking boots is difficult. Keen boots fit my 13EE foot well with comfortable room for proper hiking socks.  The fit provides support on every terrain encountered.  That said, I've only logged about 25 miles so far breaking in the boot prior to an upcoming trip.  Probably another 25 will be required for long days.  Consider ample use prior to any long use as they are quite stiff.  All day wear is possible but taking them off at days end is welcome.<br /><br />I also use a Keen Targhee II boot which have a couple hundred miles.  Those took less use to feel flexible for long distance all day use.  Other boots I've used were two pairs of New Balance 1569 were very comfortable but wear quickly ~ 400 miles.
