If you are referring to the Hi-Tech desert magnums; I wore those on my last tour to The 'Stan. personally I love those boots. Comfort, good foot bed/insole inside, breathe relatively well, dry quick, cheap! $76 USD, and readily available at the PX on KAF. Not to bad in the winter either if you use a good thick sock; however proper winter boots are the best route
First pair I bought had the heal cup crack so I sent an email to Hi-Tech, they sent me an authorization letter to get a new pair from AAFES free of charge.
Life expectancy is about one 6 month tour of hard use, but since they are so cheap I bought two pair; the second never came out of the box and I can still wear my old ones. just my personal opinion
