New Balance Men's Fresh Foam X Hierro V9 Trail Runners (Style D4CB)

Our review of the New Balance Fresh Foam X Hierro v9 finds it best suited for men who want a cushioned, protective trail shoe that also works for mixed surfaces. The single biggest reason to buy is the dual density Fresh Foam X midsole, which delivers a noticeably plush ride with firmer support beneath the foot for longer days on uneven trails. The shoe balances comfort and protection through a knit upper with a gusseted tongue and Toe Protect, making it a practical pick for hikers and trail runners who prioritize cushioning without sacrificing durability.

Key Features

• Dual density Fresh Foam X: Provides plush underfoot cushioning while the firmer layer improves stability over roots and rocks for sustained comfort on long runs.
• Bio-based midsole content: Incorporates approximately 3% renewable materials to reduce carbon footprint while maintaining the foam's responsive feel for trail miles.
• Vibram outsole: Offers superior grip and a revamped tread pattern with deeper 6mm lugs to enhance traction on wet and dry terrain.
• Traction Lug technology: Delivers dependable bite on loose or muddy surfaces, improving confidence during technical descents and climbs.
• Gusseted tongue and knit upper: Keeps debris out and breathes well, giving a secure, comfortable fit for all-day trail use.

Who It's For

The Hierro v9 is ideal for trail runners and outdoor enthusiasts who want a cushioned ride with protective features for rugged terrain. It suits those who split time between singletrack and harder-packed surfaces and who appreciate comfort on longer outings.

Runners seeking a minimalist, ultra-light race shoe or those needing a very narrow, performance race last should look elsewhere; some customers report variability in fit and occasional impressions that the shoe runs small, so try them on or size carefully if you have a precise fit requirement.
