I've used the old CF leather boots for years, for airsoft and various other activities. I've had various things happen to me that I know would have resulted in injuries, except the rigidity of the boot kept my ankle from twisting far enough for that to happen.
I also have a pair of Bellvilles now (USMC). Haven't worn them out, but they're extremely comfortable. They almost feel like my Columbia Tigertooth hiking shoes.
