What can I say; lace system is fantastic, grip is amazing, and it sheds debris great. I feel like a gazelle in these as I bound off logs and rock! Cons? If you are running on pavement very far to get to the woods, don't bother. They are like cleats and the hard surface will wear them down quickly. Also if you are doing light flat trail jogging, you can do better. But if you want to rip through the woods and race like a chased animal look no farther. They do have narrower soles; no wide flanged soles here. It takes some getting used to as it's easier to roll an ankle but once you get used to it the others feel like boards on your feet vs barefoot. Only other two cons I can think of is they don't breathe as well in really hot weather vs a few others. Not bad at all, but others are better at the loss of protection though. And second, they don't do as well on slippery rock surfaces as a few others. Again, not bad, but others are better. Finally please realize that there are cold climate versions as well that are more waterproof and warmer. Flat trails I use minimalist shoes. Hills, heading across river rocks, rooted and logged trails I reach for these and nothing else.
