Right boot for the environment and job, there is no one boot for everything.
Currently I am working in the Desert Southwest, in terrain very much like a certain 'stan. So much so, that folks from the John Wayne School for Boys come visit before deploying.
Having said that, I am REALLY LOVING my Danner 453 GTX boots. Less expensive than the Danner Combat Hiker, and really getting the job done for this old fat man, who just can't hump the hills like I used to.
