Based on the HRT design, this is a nice mid-height variant. The usual fancy 5.11 materials are used being lined with Coolmax® and Drilex® including a Suede and nylon upper. The end result is a good middle ground of a pretty comfy, but breathable boot. The laces and sole appear to be the same as the Urban HRT boot, but the zipper is one of the features unique to the HRT line that makes this boot the Advancer.
I like the zippers a lot for allowing me to put them on and off quickly, however, after a long day, the zippers do sometimes slide down on their own. A simple velcro tab or snap would solve the zipper drift problem very easily. I'm always a fan of the pull tabs on the back, but I would like to see a bigger loop. My finger, which is pretty small, has trouble fitting in the loop. It is not an issue, but I thought I would note the soles make a more "clappy" noise on hard surfaces when running than most boots. Currently available in Coyote. More to come as I keep wearing...
