I'm not sure the support or the fit would be all that well for a dedicated trail running shoe, but for a good general purpose, light hiking shoe with plenty of grip, these are a great deal.
I have worn them all day, every day throughout a very hot summer, over a variety of surfaces from loam to sand; rocks, wood debris and concrete, and found them cool, comfortable, and durable. Best of all, the soles have just enough cleat to provide good traction without hopelessly trapping mud and soft soil. After all, if they did, they wouldn't be good trail shoes.
