Expert Review Sources

  • RoadTrailRun : 86.9 / 100 — « Calibrated with a 4.2 mm drop and weighing 309 g, the New Balance Fresh Foam X Hierro v9 pairs a fluid forefoot roll with leg-saving Fresh Foam X cushioning (309 g). A smart choice for runners looking for a 4.2 mm drop and consistent performance all season long. »
  • iRunFar : 86.0 / 100 — « Built by New Balance around the Fresh Foam X midsole, the Fresh Foam X Hierro v9 locks the foot down securely on steep descents while preserving muscular energy over long hours (a 4.2 mm drop). Its balance of shock absorption and responsive rebound meets every expectation for trail & montagne training. »
  • RunRepeat : 85.6 / 100 — « The New Balance Fresh Foam X Hierro v9 is a bold reboot of the series. We found that it ditches its former flexible-and-grounded vibe for a stiff, max-cushioned platform with low-drop geometry and a rocker-assisted ride. While the new high-stack profile won’t please everyone, we were impressed by the plush foam, ultra-grippy Vibram Megagrip outsole, and trail-ready materials. However, if you’re chasing that familiar Hierro ride, prepare for a wake-up call. »
