Working in Kuwait as a contractor and my job requires tan desert boots. Our issued ones are horrible (5.11 ATAC)  This is the 2nd pair of boots I have bought in 2 years and they are very comfortable.  It took about a week for some minor breaking in around the top potion of the boot in the ankle area.  Once broken in I have to say I do notice when I am walking over rocks (we have a lot of them on our camps) that I barely feel them due to the soles of the boot.

One thing I will have to say is that they are not the "coolest" boot I have worn.  I was working outside 12 hours a day 6 days a week in temps that hit higher then 140+ degrees on some days and if I had these on I know my feet would get very hot. I am working inside currently and my feet tend to get warm some days. I am making the comparison to my pair that I ended up retiring after 1.5 years of wear, Magnum Elite Spider, which I could feel the air flow through the boot which keep my feet cooler (If that even sounds possible in the desert heat).
