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

Our review of the New Balance Fresh Foam X Hierro v9 finds it best suited to trail runners who want plush cushioning and confident traction for varied terrain. The single biggest reason to buy is the dual density Fresh Foam X midsole, which delivers noticeably softer impact protection while still feeling stable underfoot on roots and rocks. Reviewers praised the comfort and build quality, and the combination of a Vibram outsole and 6mm lugs makes these shoes a reliable option for wet or dry singletrack.

Key Features

• Dual density Fresh Foam X: Provides a cushioned, responsive ride that reduces fatigue on long runs and technical descents.
• Bio-based midsole content: Incorporates renewable materials to lower carbon footprint without sacrificing the soft feel of the foam.
• Vibram outsole with 6mm lugs: Delivers superior grip and stability on loose, wet, or uneven trail surfaces.
• Toe Protect technology: Shields toes from rocks and roots to prevent bruising and extend shoe durability on rugged routes.
• Gusseted knit tongue: Improves fit and keeps out debris while maintaining breathability during warm-weather outings.

Who It's For

The Fresh Foam X Hierro v9 is for men who spend most runs on trail and value a plush underfoot feel paired with solid traction; hikers who want a cushioned approach shoe will also find it useful. Runners tackling mixed terrain, from packed dirt to rocky singletrack, will appreciate the lug depth and toe protection.

Those who need a very low-weight race shoe, minimal drop for aggressive forefoot runners, or a narrow racing fit should look elsewhere; some customers reported mixed experiences with sizing and a roomier knit upper that favors comfort over a race fit.
