New Balance Women's Fresh Foam X Hierro V9 Trail Runners (Style 8DY9)

Our review of the Fresh Foam X Hierro v9 finds these women's trail runners best for hikers and runners who want a cushioned, secure ride on rugged routes. The single biggest reason to buy is the dual density Fresh Foam X midsole, which delivers unusually plush cushioning for a trail shoe while still feeling responsive. Built-in Toe Protect and a Vibram outsole give confidence on rock, root and wet trails, and the gusseted tongue keeps debris out so the shoes stay comfortable mile after mile.

Key Features

• Dual density Fresh Foam X: Provides the most cushioned Fresh Foam experience New Balance offers for a softer, more comfortable ride on uneven terrain.
• Bio-based midsole content: Incorporates about 3% bio-based materials to reduce carbon footprint without compromising cushioning performance.
• Toe Protect technology: Shields toes from rocks, roots and debris so users can tackle technical trails with less worry about foot injuries.
• Vibram outsole: Delivers superior grip and durable traction, improving stability across wet and dry surfaces on the trail.
• Traction Lug technology: Lug pattern enhances bite on loose and muddy ground to help maintain footing during steep or slippery sections.
• Gusseted tongue: Keeps out dirt and grit while providing a secure, comfortable fit through longer outings.

Who It's For

The Fresh Foam X Hierro v9 is ideal for women who split time between long trail runs and day hikes and prioritize underfoot comfort and protection. The plush midsole and toe protection suit walkers on rocky routes or those who stand and walk long hours on varied surfaces, while the Vibram outsole supports those who need consistent traction.

Runners seeking an ultralight race day shoe or those who need a very narrow, performance racing fit should look elsewhere; the Hierro leans toward cushioning and protection over minimal weight and a tight race-oriented profile.

Pros & Cons

Pros

• Exceptional cushioning from the dual density Fresh Foam X midsole for long comfort on trail miles.

• Excellent traction from the Vibram outsole and traction lug pattern on wet and dry terrain.

Cons
