I think it all comes down to what has been mentioned here (by me and others) and elsewhere: too many "new" (I hate to say "young" because a lot of the people I hear of pulling these types of stunts aren't in their late teens/early 20's) people think that if Johnny has something that has a high LCF, they should have it, too, regardless if they actually need it or "deserve" it. They feel it is their birthright, and they are damn well entitled to it.
There is decidedly less "fear" in new soldiers now, what with the huggy kiss "here are your rights: now go out and use them!!!!" being foisted right from the CFRC on upwards. I would've swallowed battery acid before saying "You can't make me do that!!!" to anybody with 2 days more in the Army than me (when I got in), and now it isn't uncommon to hear of new soldiers saying that to Cpl's, MCpl's, etc, etc.
Whether it's right or wrong to question certain things (cam paint tubes, aluminum cups, melmac, anthrax medication, etc) when you have doubts as to their safety and/or effectiveness can be left to the JAG, but I KNOW that I will never wear a pair of Mk III's again, even if I have to buy my own boots by collecting pop can's out of the ditch. Some swear by them: I swear at them. I wore them in their unaltered state for about 12 years, and then had them Vibram soled, and now wear alternative footwear (one pair paid for by the Crown, one pair paid for by Al). As AM mentioned, the majority of the time spent in Mk III's is in garrison, on concrete or asphalt (or surfaces laid on top of those). The pounding that your body takes is incredible and the Mk III (in it's "out of the box, with cheeseball liners") provides next to no cushioning. The Vibram sole itself does little (other than provide a sometimes better/sometimes worse outer sole): it is the cushioning between the outer sole and the boot that provides the cushioning one needs. Take a look at ANY quality boot (and even lower quality boot) and they provide this. Same goes for running shoes, and even dress shoes now. It's called "technology". Go from wearing a pair of "good" boots (Danners, Matterhorns, Corcorans) or even MK III's with Vibram soles to MKIII's (in unaltered state) with issue (not Spenco insoles, which are given out at UMS, not clothing stores..... hmmmm, what does that tell you?), and it feels like you are walking around with hockey pucks strapped to your feet (especially when it is near freezing).
Time for the CF to get with it, and invest in new boots (yes the CTS programme is procuring them, but I shant hold my breath waiting) that can be worn EVERY day (the WW boots suck mad ass when you are a Carpet Commando or Hangar Queen (and in the field for that matter), unless you like having feet that roast in the summer).
Anyway, my rant out of the way, and for you young 'uns who say "Well, he won't wear the Mk III's, why should I?": read how long I went without, and also note that I paid for my own (and was willing to pay for resoling of the MK III's (a new pair), but the system ran out). If it means that much to you, you have to be willing to spend some money out of yer own pocket. And finding a sympathetic MO to sign the chit that says you can wear them ;D (or avoid your RSM like the plague).
