I loved the Mountain Masochist I, and this update is still a solid trail running shoe. There is a good balance of stability and cushioning that leads to comfort both on the trails and on the half mile of pavement I run to get to the trails. Like the prior version, this still a good shoe for a runner with a narrower, high-arched, low volume foot, but I've had to work a little harder getting the upper nice and snug without getting it too tight. This may get better as they break in. Overall, this model still has the grippy sole, reliable tread, tough exterior, and blend of cushion and stability that makes the Mountain Masochist my go-to trail running shoe.
