Man I would try the Denali's or the Western Guides. Both great boots, the Western Guides are a little stiffer and sturdier but the denalis are probably the most comfortable boot that i have tried on. If you get the chance to try these on I would highly recommend it.
Check out this other thread I started - I'm really just looking for a good backpacking boot that fits. http://www.rokslide.com/forums/footwear/48171-boot-shopping-history-wide-feet.html
