New Balance Men's Fresh Foam X Hierro V9 Trail Runners - Cushioned out

Our review of the New Balance Men's Fresh Foam X Hierro V9 Trail Runners finds them best suited to trail runners and hikers who prioritize plush underfoot cushioning plus reliable grip on varied terrain. The single biggest reason to buy is the dual-density Fresh Foam X midsole, which combines soft, responsive cushioning with a firmer layer for stability, making long outings noticeably more comfortable without feeling unstable. They feel built for miles on uneven trails while still working for casual pavement use when needed.

Key Features

• Dual-density Fresh Foam X: Delivers the most cushioned Fresh Foam experience with a softer top layer and a firmer base for a balance of comfort and stability.
• Bio-based midsole content: Approximately 3% of the midsole material is from renewable resources, reducing environmental impact for eco-minded runners.
• Vibram outsole: A redesigned tread pattern with 6mm lugs provides superior grip and confidence over wet and loose terrain.
• Toe Protect technology: Shields toes from rocks and roots to improve durability and reduce foot discomfort on technical trails.
• Gusseted knit tongue: Helps keep out debris while offering a breathable, secure fit for varied trail conditions.

Who It's For

The Hierro V9 is aimed at trail runners and hikers who want a plush, cushioned ride without sacrificing traction; the combination of deep lugs and the Vibram rubber makes them a good choice for muddy or rocky routes. They also suit runners who want a comfortable shoe for longer training days where underfoot softness reduces fatigue.

Runners seeking a very low-profile, race-ready trail shoe or those who need a strict, roomy fit should look elsewhere, as some customers report the sizing varies and the knit upper gives a closer fit than traditional leather or mesh trail models.
