This is the second pair of Dunham Boat Shoes I have purchased.  They are very comfortable for my very wide feet.  It is hard to find shoes in a 6E width, and Dunham is one of the few companies that makes them.
These are ventilated on the sides, which will be great this summer, as I live in the desert.  Boat shoes in the desert?  Works for me because of the ventilation, comfort and the fact I don't have to wear socks.  They say they are waterproof, which means I can rinse them out when they get stinky.  Because of the ventilation, they won't keep water out, but can stand up to getting wet.
I have several pairs of Dunhams, from boat shoes to boots to dress shoes, and they are all great quality for the price.  I recommend them highly.
