Work as a contractor in Kuwait and am on my feet 13+hrs a day, 6 days a week.  Was wearing a pair of company issued boots and within days I could barely walk because they were heavy weight material and my feet would sweet in the 130-140 degree heat and caused blisters.

I bought a pair of these boots and it was instant relief.  You could feel the airflow in these boots even on the hottest of days.  They are like wearing a pair of comfortable sneakers.

The only thing I wasn't sure on was the material they were made out of.  A year later I have a rip on the outside right behind the toe suede area and the cloth "eyelet" in the middle of the lacing wore out and tore and the others are about to go as well.  They would have probably held up better if I didn't work the hours I do but by far up there with the best boots I have had next to the pair of jungle boots I had issued to me when I was stationed in Panama.  Those ones fell apart because they are so old and not from the extreme use I got out of them.
