The Nike Air Zoom Terra Kiger 7 is a great shoe for fast and flowy trails. It has an outstanding balance of protection and sensitivity and feels like it has way more cushion than what's there. These shoes can take you from the pavement to the fire roads to winding single track with ease, though mountain runners will want a stickier rubber for running over exposed granite (like the La Sportiva Kaptiva). For everyone else, the Terra Kiger is a worthy choice that we would not hesitate to add to our quiver of best shoes..
