If you're looking for casual sneakers, hobodom is rarely far behind. Simple, my recently passed but still favorite shoe-maker is... (googles) still dead, and only go-aheads/thongs are available through Zappos.com and Shoes.com.
Shit.
I have wide feet as well, and quite a bit of trouble finding shoes which fit well. Simples always fit well. New Balance also fit me well, but are seriously dry in the design department.
You might look at Rockport for serviceable, comfortable, partway dress-up shoes. I've had a pair for 20 years, and they're the only dress shoes in which I'm comfortable.
