I have two pair of Fugitive GTXs. They are THE boot. They are being issued now for "use in mountainous terrain".
The FSN95s were issued to a couple guys I know in the SOF community. They love them.
I wear the Lowa Vento QC mid in the summer because they breathe extremely well, and are very supportive and comfortable. Any GTX boot will get a bit too warm in the summer during prolonged time outdoors. I bought the Lowas because of this.
I had a pair of Merrel Ventilators. They rubbed my Achilles tendon area, had poor arch support, and weren't constructed well. I doubt I will ever buy a pair of Merrels again.
I have a pair of Oakley SI Assault Temperate Weather boots, I got in Bagram, that I wear when uniformity matters. They are durable. They have a better sole feel than my issued ICBs or ACBs, but still don't compare to the civilian boots.
For a civilian hiking boot, you cannot go wrong with either the FSN95 GTX or the Fugitive GTX. Asolo also has a great warranty.
