To follow up...
I struck out at Sportsman's Warehouse. I was able to get my hands on the Crispi Nevada, which seemed like an excellent boot, but they didn't stock wide sizes. I spend a bunch of time at REI the other day trying on boots, and it was a very similar experience. They sell a variety of boots in wide, but they don't stock many in store. Of the wides available, they tended to be in what I would consider narrower brands, and none of them would cut it for me. I tried the Lowa Camino GTX... Very high quality boot, but it was a little to narrow even in wide. They offered Keen boots, but only standard width in store. The standard width Keen is as wide as most of the wides in other brands, so I'm confident that a wide Keen would do the trick, except that they don't offer anything like I was looking for in a boot.
I received some recommendations for Meindl, including here, but I couldn't find anywhere around me that stocked them. I figured out what size I would need in Mendl, and I lucked out that someone was selling a pair of ultralight hunters just down the road from me. They were insulated, which is not what I was looking for, but they fit great and they were only $60. Buying them seemed like a no brainer at that price. Especially since they were only worn once. I wore these 400g insulated boots around Phoenix with doubled up wool socks to get a feel for them before ordering a pair of uninsulated boots. Besides my feet being extremely hot, I have to say that these are some of the finest boots I have ever owned.
People say the Meindl run large, and their own website says to buy a full size down from what you typically would wear. I measure 11E, but I normally buy an 11.5 so I have a little space for my toes to not jam into the front of the boot as they say to do. With the doubled up socks (heavy wool w/ liners) a half size down worked well for me at size 11 wide in the Meindl boot. For the uninsulated pairs that I'm going to order, I'll be wearing a thinner sock, and I'm planning to order a 10.5 wide. I hope that size reference helps someone out.
Thank you to everyone for the recommendations!
