I love the traction!  It is a great shoe for trail running for me and my wife.  Both my wife have a pair and we love them.  I feel that running on the trail is much more effortless with these shoes.  My only complaint is that for distances 5+ miles I start to develop a blister on one of my toes.  This hasn't ever been a problem for me with other shoes.  It does have a narrow toe box which is likely why I'm getting the blister.  If they made it just slightly wider it would be be by far the best running shoe I've ever tried.
