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

Our review of the Fresh Foam X Hierro v9 finds it best suited for men who spend serious time on varied trails and want a plush ride without sacrificing grip. The single biggest reason to buy is the dual-density Fresh Foam X midsole, which layers a soft, responsive top with a firmer base to deliver notable cushioning and stability over rocks and roots. Built with a knit upper and gusseted tongue, this shoe balances comfort and debris protection so it performs well on long runs and mixed-surface outings.

Key Features

• Dual-density Fresh Foam X: Provides a cushioned yet stable underfoot feel that helps reduce impact on long descents and varied terrain.
• Bio-based midsole content: Adds renewable materials to the foam for a slightly lower carbon footprint while maintaining the soft ride.
• Vibram outsole with 6mm lugs: Delivers aggressive traction and confidence on loose, wet, and rocky surfaces.
• Toe Protect technology: Shields toes from rocks and roots to extend durability on rough trails.
• Gusseted knit tongue: Keeps debris out while offering a secure, breathable fit for longer runs.
• Traction Lug technology: Improves grip in both wet and dry conditions for better performance across trail types.

Who It's For

The Fresh Foam X Hierro v9 is aimed at trail runners and hikers who want a plush, comfortable shoe that still offers technical protection and grip. It is a good choice for weekend adventurers, runners tackling long miles, or anyone who alternates between trail and hardpack and values a softer midsole.

Runners who need an ultra-lightweight race shoe or those who prefer minimal cushioning for short, fast efforts should look elsewhere, as the Hierro v9 prioritizes durability and comfort over extreme weight savings or minimal drop performance.

Pros & Cons
