Good news! Trail shoes in general are starting to get really good. Like the quick, responsive New Balance 904
, the GRID Harrier has an emphasis on traction and speed. It too places the foot low to the ground for a positive feel, and its grip is good for all but the worst mud. But otherwise the shoes have quite different characters. The Harrier has a softer ride, which makes it more forgiving but gives you a slightly less direct feel for the ground. Its also built on a much more curved last, which encourages a faster foot movement, and by encouraging pronation also has the side-benefit of helping to reduce the risk of sprains. Theres a medial post, but really this serves more to keep the effect of the curved last in check than to add stability its not a shoe for overpronators. In fact, you can think of it as a trail-going version of the GRID Swerve, Sauconys longstanding racer-trainer. Also of note is the water-repellent upper, which has an unusually narrow forefoot fit for a Saucony shoe.
A good option for trail races or faster-paced off-road training, the Harrier scores well on grip and responsiveness. Unless youre a heavy or unstable runner, it should be on your off-road shortlist.
