Max Cushion Meets Mountain Grip

For runners who want to go farther, longer, and with more protection underfoot, the New Balance Fresh Foam X Hierro v9 is your ultra-capable trail companion. Designed for long-distance comfort, rugged terrain, and all-day adventures, this max-cushion trail shoe brings together plush Fresh Foam X softness and aggressive Vibram Megagrip tractionfor confident movement across any landscape.

In this latest version, the Hierro evolves by incorporating the best features of the v8 and New Balance’s trail-favorite More Trail — with higher stack height, a more balanced 4mm drop, and a dual-density Fresh Foam X midsole that strikes the perfect blend of soft cushioning and trail-ready stability. A firmer base layer keeps your ride grounded and controlled, while the top layer cradles your foot in comfort for long hours on your feet.

Below, the Vibram Megagrip outsole features burlier 4.5mm lugs with new micro-traction detailing, giving you confidence on loose dirt, wet rock, and unpredictable terrain. Up top, the engineered mesh upper has been refined for a softer fit with abrasion-resistant overlays, a gusseted tongue, and Toe Protect forefoot shielding.

Whether you’re venturing into technical mountain terrain, grinding out base miles on rolling trails, or simply looking for a shoe that can handle your longest days with comfort and grip, the Hierro v9 delivers dependable performance and plush protection in equal measure.

• Trail runners and hikers seeking max-cushion comfort and traction for long distances
