New Balance Fresh Foam X Hierro v9

The New Balance Fresh Foam X Hierro v9 is a max-cushion trail runner built for high-mileage comfort on mixed terrain, from hardpack and gravel to mellow singletrack. Its dual-density Fresh Foam X midsole leans plush on top but adds a steadier base underneath, giving you a protected, confidence-inspiring ride when the trail gets choppy. Underfoot, a redesigned Vibram Megagrip outsole is tuned for dependable wet/dry grip, while the knit-inspired upper and gusseted tongue help lock in the midfoot and keep trail debris from sneaking in.
