The goretex boots have more problems then perks as far as I'm concerned...
- Big clunky soles, particularly compared to the MkIII boots, which, for all their faults, my have broken in to the point of being slippers... I'm always terrified I'm going to trip and fall off wearing the goretex boots when you're scrambling around on top of a truck trying to arrange a pent-house. Keep expecting the soles to catch in somthing. Glued soles instead of stiched soles would be nice.
- The liner takes forever to dry, goretex is as good at keeping water in as it is at keeping it out. The boots are great if you're wearing them in one spot, and don't go over the top in water, but once you fill them, they're a write off for the next few days. Just sweating in them is enough to dampen them to the point where they're cold and ineffective. An uninsulated goretex boot with heavy socks would be better.
- In the winter, because the boot often traps sweat, the boots freeze overnight, and are difficult to put on/walk in in the morning.
- Slippery on ice. Yes, the vibram soles are durable, but is there any sense in having a sole that will out last the boot?
There are far better goretex boots out there then the Canadian army issued ones, if you're buying them civvy side, don't waste your money on the issued ones.
