These boots were great for the first 2 months of my deployment; however for some reason the left boot developed a gash in the outer lateral side.  Amazon accepted a return and exchange.  In general the boots were comfortable enough to wear all day, a little warm for hot environments, the Kevlar toe protection was the best feature, as it is a marked difference from the steel toe. The boots are light, and comfortable.  Not recommended for long walks.  Otherwise good value and fair enough quality.  Hides the tan dust really well.
