hindsight often makes common sense clearer. I bought these for a spartan race (a super) and expect that they will perform well. Ive clocked 50 road miles in them so far and the grip has worn down by about 75 percent. Granted most of these miles have been in the road; I'm sure now if those miles were on trails (clocked 15 on trails) they wouldn't be nearly as worn.<br /><br />The support is great; the quick lace is an incredible feature (that doesn't loosen); and the breathable fabric make this a great trail running shoe.  The dumb one that ran a bunch of road miles on it (hence the still-high review).
