The Terrafly has now been discontinued so is at a great price! It was designed as a shoe which would handle both road and trail running. If you are running groomed trails in a park, or cycle trails, or bush walking, it is a great shoe that is also a grippy road shoe. It doesn't have the traction needed for mud, slush and mountains, but excellent for parks and domains. It is also a very comfortable leisure shoe – pre and post race - and looks great on the podium too!
