I thought boots were boots until I bought these.  They.  Feel.  Incredible.  From the second I put them on they were like clouds on my feet.
My only complaint would be that the laces broke, but that may have had something to do with the fact that I was in Afghanistan and they probably were "overused" or dried out.
They have great ankle support.  If you're thinking about buying those Nike boots and have weak ankles, I would strongly advise against it.
