These shoes are everything that the video reviews say they are.  They have wonderful heel support and the lace system came very naturally to me.  I know others have had a minor issue with them, but I think they were over-thinking it.  Just hold the button thing and pull the lace back and squeeze it to release.  It's quite a beautiful system really.  The aesthetics are very spider-man-like since I chose the red pair.  The price gap between all the colors surprised me and ultimately chose the color for me.  As far as trails go they absorbed most of the shock from roots, rocks etc and they handled the wet mud spots really well.
