New Balance Fresh Foam X Hierro V9 Trail Runners - Cushioned Grip in

Our review of the Fresh Foam X Hierro v9 finds a trail runner built for long days on technical routes; the biggest reason to buy is the plush dual-density Fresh Foam X midsole that delivers a noticeably softer ride without sacrificing underfoot stability. These shoes are for runners who want confident traction from a redesigned Vibram outsole and protection from trail debris, with a knit upper and gusseted tongue that help keep grit out while maintaining breathability.

Key Features

• Fresh Foam X midsole: Dual-density cushioning blends plush comfort with a firmer layer beneath for more stable landings on uneven trails.
• Bio-based content: Approximately 3% of the midsole foam is made from renewable resources, reducing the shoe's carbon footprint while keeping the same responsive feel.
• Vibram outsole: A revamped tread pattern and 6mm lugs provide superior grip and confidence on wet and dry terrain.
• Toe Protect technology: Reinforced protection guards toes from rocks and roots to extend durability during rugged outings.
• Gusseted tongue: The knit upper with a gusseted tongue keeps debris out and creates a secure, comfortable fit for varied trail conditions.

Who It's For

These trail shoes suit runners and hikers who prioritize cushioning and traction on mixed or technical terrain, and who appreciate an upper that breathes yet resists trail debris. The Hierro v9 is a good match for long training runs, gravel paths, and day hikes where comfort and toe protection matter.

Runners seeking an ultra-lightweight race shoe or a narrow, performance racer may want a different model, and those needing a radically wide toe box should verify fit since customers report mixed feedback about sizing and fit.
