I have to admit, I wasn't sure what to expect out of these boots.  I'm not a soldier but I figured that if the 'boys' wear these then they have to be pretty good.  Guess what....THEY ARE.  These are very nice boots and they are very comfortable.  I recently did a 15 mile hike in these and not a single blister.  Even ran 4 or 5 miles in these as well.  I really can't say enough good things about them.  I've got 30 miles in with these boots now and they rock.
