New Balance Men's Fresh Foam X Hierro V9 Trail Runners (Style L89Q)

In this review the New Balance Men's Fresh Foam X Hierro V9 Trail Runners earn a recommendation for runners and hikers who prioritize plush cushioning and dependable grip on technical trails. The single biggest reason to buy is the dual density Fresh Foam X midsole, which pairs a soft, responsive top layer with a firmer underfoot platform to deliver comfort without sacrificing stability during long miles or uneven terrain.

Key Features

• Dual density midsole: The Fresh Foam X construction provides a plush ride with a firmer base layer for added stability on rocky or rooty trails.
• Bio-based content: Approximately 3% bio-based foam reduces reliance on petroleum-derived materials while maintaining midsole performance.
• Toe Protect technology: A reinforced toe area shields feet from rocks, roots and debris for increased durability in rugged conditions.
• Vibram outsole: A Vibram rubber sole with redesigned tread and deep 6mm lugs delivers consistent traction on wet and dry ground.
• Traction Lug technology: Directional lug pattern enhances grip and braking on descents and technical ascents.
• Gusseted tongue: The knit upper with gusseted tongue improves fit and prevents loose dirt from entering the shoe.

Who It's For

The Fresh Foam X Hierro V9 is best for trail runners and fast hikers who want a comfortable daily trainer that can handle varied terrain, including muddy singletrack and rocky approaches. The cushioning and lug depth suit longer outings where foot comfort matters and traction is essential.

Shoppers who need a minimalist, ultra-light racer or those who require a very wide toe box should look elsewhere, since fit reports are mixed and the shoe prioritizes midsole plushness and protection over a barefoot feel.

Pros & Cons
