Merrell Moabs are some of the most popular shoes I've seen on the dg course. They come in wide sizes, as well as at least two kinds of waterproof in addition to the "ventilator" version which breathes extremely well. Merrell Moab Ventilators have been my everyday shoes for more years than I can remember. When I wear out one pair, I go to REI and get another. The only thing I don't like is the round laces, which tend to come untied even when I double knot them. Otherwise the comfort is about as good as I've found for my "duck feet," which are wide in the toes but narrow in the heels. I've also discovered that Superfeet, my insole of choice, makes wide insoles as well, and my feet have never been happier.
