The Consensus

9Overall score
Comfortable and stylish all-round trail running shoe
Have you ever pegged New Balance as a brand for trail shoes? If your answer is no, you might want to reconsider! The new Hierro v6 is a solid upgrade for the series that is not only about looks: it delivers comfort and performance!

Let’s discuss the thick, Fresh Foam X midsole for a second—because it’s built for comfort. With an even blend of cushion and responsiveness, the midsole is designed to absorb the shock of off-road debris and gravel. Impressively, the Hierro 6 is protective without using a rock plate, ensuring a comfortable and safe ride. Meanwhile, the shoe’s upper is much improved from previous versions and is made with sustainable materials as a bonus. It cradles the top of the foot with a snugness that locks feet in place. The fit is true to size. Lastly, the durable outsole uses Vibram MegaGrip material, which proves effectively grippy yet versatile on various surfaces. While it may not be the best option for soft terrains, it will do well in most situations.

Users of the Hierro v6 were overall happy with the way it performed. The only major complaint was weight, a prerequisite to most trail shoes. The v6 is no exception and weighs 337 g/11.9 oz, which is a lot, though this model shed 20 grams/0.7 oz from its predecessor. Also, while the shoe can technically double for road and trail use, its performance is subpar on flat pavement. It’s likely due to larger lugs, making the shoe optimal for more technical terrain.

Overall, New Balance’s latest Hierro model is a comfortable option that performs well in most conditions. Version 6 can go the distance smoothly and—the cherry on top—can retire as a sleek sneaker once its trail career is over.
