Boots just for riding or are you going to want to some walking/hiking in them too?
The thing that sucks about living in the sticks is not being able to try stuff on before you buy it. If you're around SLC, maybe find a Cyclegear or similar shop and try a bunch on. That's my two cents. I suggest that because I have a very difficult time finding footwear that fits and is comfortable. I should get some dual sport boots myself -- protect the ankle and all that but I dread the day I actually start trying them on.
