I'm currently rocking Salomon Forces XA Pro 3D Mid and Quest 4D GTX boots depending on weather conditions and type of shooting. I believe the Forces models of these are just reskinned commercial offerings, so you would do well to read the reviews of those. The Quests are a hiking boot and I've found them real comfy, but as is common with these type of boots if you need any real tactility in your feet then look elsewhere. The XA Pro 3D Mid has a lower shank, weighs less, and is more breathable than the Quest, but is built off the same chassis so it's very supportive and much easier for daily wear. I'd consider and recommend them (in Mid height) as the next step up in burliness from the Forces Speed Assault model, which I have no experience with. The biggest difference between the XA Pro 3D (Mid) and Speed Assault appears to be the sole/lug design, so I'd examine those to see which is best for your use.
I have a pair of 5.11 ATACs as well, but I wear them a lot less now that I have the Salomons. I don't believe Salomon boots are available in any wide sizes either, so be warned. Those Z6S Lowa boots get good reviews, but none of wide footed friends can wear Lowa boots comfortably so be aware. For wide feet, I'll echo the Reebok suggetions - my wide footed friends really like them.
