Not that I want to ge into a pissing contest here but that is a pretty harsh stand to take on an issue like this. Considering everyone has different needs and no troops feet are the same I would have to disagree. How many of those 10 000 sizes are actually available? I know in my experience I went through the whole computer scan, two sock trial, sizing debacle and was issued a pair of CWWBoots that where too wide. I wasn't permitted to size myself at the initial issue (sausage machine) and knew categorically that once wet and stretched they would never do. Even after the requisite wait and subsequent issue of a narrower pair they still didn't fit like I would have expected. Then there is the whole traction on icey terrain issue. Anyway, having said all that, there are some of my peers that swear by them.
Personally, I liked the MkIII resoled with Vibram. I also use Jungle boots with Vibram resole and had Bertrand's reinforce the canvas strip at the back with sewn on leather because they always seem to let go there. I use Hi Techs in garrison because my feet sweat a lot. I use Danner Acadias in cold/wet weather environments. I use Hanwag Special Forces GTX with Gators in rugged terrain because they are Black, Goretex, have a full rand, and the 3/4 shank can't be beat for carrying heavy loads on uneven terrain.
I guess the point I'm trying to make is that sometimes one's personal preference and the argument of uniformity has to take a backseat to what is effective for the lowest common denominator of mobility assets - The 'Black Cadillacs'.
