I wore these to day hike Tallgrass Prairie, KS; Wheeler Peak, NM, and various day hikes in CO and now wear them to work while on my feet more than half the day. These did not rub or cause blisters on any of the hikes. Out of the box, I broke them in by walking the dog a few weeks prior to the Wheeler Peak vacation. I am over 50 and have a small foot with a mid-high arch. These keep your feet comfortable and relatively dry. They are vented, and the arch support is good. The sole is a thin cushion and after a long day you might wish you had put superfeet or some other cushion in them.  I double-knot the laces so they stay. Laces are somewhat difficult to adjust as your feet swell on the trail.
