New Balance Fresh Foam X Hierro V8 Trail Running Shoe - Cushioned 90%

In this review the New Balance Fresh Foam X Hierro V8 is judged as a trail shoe for runners who want a well-cushioned, durable option for off-road miles. The single biggest reason to buy is the Fresh Foam X midsole foam, which delivers noticeably plush cushioning with about 40% bio-based content for a softer ride and a smaller carbon footprint. The shoe pairs that cushioning with a Vibram Eco-Step Natural Outsole and Micro-Traction Lug pattern for a purposeful balance of comfort and grip on varied terrain.

Key Features

• Fresh Foam X midsole: Provides the most cushioned Fresh Foam experience New Balance offers, making long trail runs feel less fatiguing.
• Bio-based foam content: Roughly 40% of the midsole foam is made from renewable resources, which reduces the shoe's reliance on petroleum-derived materials.
• Vibram Eco-Step Natural Outsole: A durable outsole made from over 90% non petroleum-based ingredients that aims to hold up on rocky, muddy trails.
• Micro-Traction Lug design: Lug pattern from Vibram helps with multi-directional grip and shed mud more effectively than a flat trail sole.
• Breathable, protected upper: The upper balances airflow and coverage so feet stay ventilated without feeling overly exposed to trail debris.

Who It's For

The Hierro V8 is best for recreational and long-distance trail runners who prioritize cushioning and durability over minimalist, fast-paced performance. It suits runners who want supportive arch feel and lasting midsole comfort for training runs, ultra-distance training, or long hikes where underfoot comfort matters.

Runners seeking a very lightweight, race-day speed shoe or those who need an extremely narrow fit should look elsewhere; some customers report the fit runs small or varies between widths, and the plush midsole makes it heavier than minimal trail racers.

Pros & Cons

Pros

• Excellent cushioning and long-lasting comfort from the Fresh Foam X midsole.
• Environmentally minded materials with roughly 40% bio-based foam and an Eco-Step outsole made from mostly non petroleum inputs.

• Breathable upper that still offers protection from trail debris.

Cons

• Fit is mixed for some users and can run small, so trying before buying or sizing up may be necessary.
• Grip received mixed feedback in wet or very slick conditions despite the Vibram outsole.
