Mark,
I've got to concur in regard to what you say about doing fast-paced load marches vs. general soldiering in the field with a Gore-Tex boot. When I was out in Pendleton doing a 15K in July of 2002 I was wearing my Matterhorn ICB gore-tex boots and my feet had sweated so much that I was literally wringing the moisture out of my socks. The gore-tex had reached its saturation point and couldn't pass any more moisture through, so it was like wearing a pair of rubber boots, with all the sweat collecting inside of them. Luckily my feet didn't get any serious blisters, but I could see how the combination of the moisture, heat and friction causing skin on the foot to sheave off very easily, resulting in some seriously nasty foot sores.
Doing the same march a week later I switched over to the issue jungle boots. The soles were not nearly as comfortable, but the lack of a gore-tex liner allowed my feet to breath, which resulted in them staying alot drier, lessening the chance of footsores/blisters developing.
I currently use the USMC jungle/desert non-goretex boot year round, but in times where I'm not doing any ruck marches I wear them with a set of Rocky Gore-Tex oversocks, and for any type of long march, I'll strip the gore-tex socks off. Works pretty well thus far.
I've noticed that with most of my gore-tex boots (have the issue Matterhorn ICB plus a pair of Matterhorn versions of the Danner Ft. Lewis) that the cambrelle lining and gore-tex will wear through in the toebox and other areas after a couple years, thus allowing water to enter through the leather into the boot's interior. The boot otherwise is fine, and by that point in time has probably become so broken in it's very comfortable to wear. Unfortunately, the cost of sending the boot back to Danner or whoever for a rebuild of the liner is expensive. Additionally, unless you wash your boots occassionally, salts, dirt and body oil will build up in the liner and Gore-Tex layer of the boot, making it breath less. With the oversocks, I can simply throw them in the washing machine when they become soiled, or replace them entirely when they wear out.
If CTS does introduce a 'temperate' non-goretex boot that utilizes a combination leather/cordura upper in the same style as the WWB, you guys will have one excellent piece of gear.
