I have had these shoes for six months and have logged hundreds of miles using them. I almost exclusively run trails in UT. Most of the trails are rocky and technical. I really like the rock plate in the forefoot, especially coming from the MT10. The shoe is very light weight. It breaths very well. I have been using them without socks. They shed water very well. I have crossed streams ankle deep and expected the shoe to feel soggy afterward, but it drained almost immediately after exiting the stream. The lugs on the outsole are outstanding. They provide good traction on dirt, road, and snow. The only place I found poor traction was on hard packed, nearly icy snow.
The only cons that I have experienced is that the sole started coming unglued at the heel after about 250 miles. I noticed it early and was able to repair it with shoe goo, and have had no further problems. Also since I run sockless I have had a problem with my shoes smelling terrible. Bad enough that my wife won't allow them in the house. A running buddy of mine also bought these shoes and uses socks and has had no odor problem.
