If you have wide flat feet you know how hard it can be to get shoes.  I normally buy new balance because they tend to have neutral soles (mostly flat and not too narrow) and they have a good variety of wide shoes.  Most times I need to get a 1/2 size larger to get a comfortable fit.  I got a 12 6e and they are very roomy.  The only other shoe that fit me well was a Drew 11 1/2 6e "boulder" hiker (about $200) but those are simply too spendy and not quite so nice for athletics.  My only dislike of this shoe is like most trainers they are not ventilated well like a running shoe.  My feet do get a little too warm during a cardio workout.
