These were comfortable, I must say.  I expect that they would have excellent traction as well - the tread is deep and the rubber is almost clingy.  However, I never wore them outside; I ended up returning them.  I thought on the picture online that these sneakers looked charcoal gray with some black and light pink.  In reality, they were completely black and the pink is quite a bit darker.  I just was not happy with the appearance of the shoes, so I sent them back.  If you just want a comfortable shoe for trail running and don't mind the all black look, give them a try.
