Meindl, bit like KSBs but dessy beige. Time will tell how hot they get when the weather warms up but the mud and clay and sandstorms and rain haven't harmed them yet. The Oakleys fell apart after 7 months in the sandpit. Before that the brit issue dessy boot was fine, ironically, I winger like fcuk about them when I was in!
I can feel my feet sweating away right now inside my Meindls; they're not bad, took no time to break in and are certainly better then my old HiTec Crapnums, which fell to pieces after a couple of months of rancid sweatiness.
Mine have been okay but I have seen a fair few examples of broken stitching and pulling of eyelets. You're right, they are quite hot; much more heavy duty than, eg, Hi-Tec, which were a bit too lightweight if anything.
If the Converse ones you are on about are the side zip jobs with the composite toe, then yep, they are good. Bought a pair in the PZ last October, still going strong, even though I'm back home. I found they needed looking after when soaked through, as the suede round the oe got a tad ropey. Very comfy though.
Old US desert boot keeps your feet cool but like most people who wear jungle boots, the panama sole goes pretty rapido. Wellco ones are cheaper than altama and if your friendly with the Canadians they can get them exchanged for you. Also the Bates desert boots are not bad and can be bought out of the PX.
I used Magnum dessies I was issued and had no problems with after six and half months in the Iraqi summer.
Frankly in 55*c heat if your feet don't sweat you need to get out of the A/C office and do some phys.
