I'm in love with this shoe. I just bought this year's newer model after putting 500 miles on the one shown here. I run a mix of trails and roads and I've got to agree with metaljonez when he says the sole is extremely soft--you'll feel the rocks if you don't watch your step. The newer model is a little stiffer there so hopefully problem solved. I just finished a marathon two weeks ago in these shoes and it is the first marathon where my feet were not sore at the end--seriously--the cushioning in these is great (I'm small 5'8 150 so bigger folks may or may not experience the same cushion).
These shoes have held up to pounding training runs, mud, rain, etc. and nothing has fallen apart. I love the boa lacing. Happy Trails! 4 stars because rocks can hurt you and if a shoe is going to be advertised for trails, it needs to have more protection.....
