This is a great shoe. It is wide, particularly in the midfoot (which I need, and many shoes do not have) and it is built with materials, that at least upon inspection, look like they will hold up well over the course of many, many trail runs. It is not flimsy in any way, nor is it as light as some ultralight trails shoes - but, I'd expect it to last longer. Traction is solid on the bottom. My first runs were a joy on trails, and not much fun on pavement. The lugs are big and deep - particularly good in soft, wet or loose conditions. However, on pavement or really hard packed dirt roads, they squirm a bit (in their defense, they are not intended for roads). My only complaint about the shoes in using them for their intended purpose is that rocks can punch through the soles pretty easily if you don't watch foot placement. I bruised the bottom of my foot on the first run in them. I attribute that to my own fault as well, but these are probably not the perfect shoes for super rocky, sharp terrain.
