New Balance Fresh Foam X Hierro V8 Trail Running Shoe - Cushion & Grip

In this review of the New Balance Fresh Foam X Hierro V8 trail running shoe, the bottom line is simple: it is for runners and hikers who want a highly cushioned, waterproof trail shoe that still feels relatively lightweight. The standout reason to buy is the updated Fresh Foam X midsole, which delivers noticeably plush cushioning and increased stack height for long days on varied terrain, while a GORE-TEX membrane keeps feet dry without suffocating breathability.

Key Features

• Fresh Foam X midsole: Provides the most cushioned Fresh Foam experience New Balance offers for long-distance comfort and shock absorption on trails.
• Bio-based content: Incorporates about 3% bio-based materials into the midsole to reduce the shoe's carbon footprint while preserving cushioning performance.
• Increased stack height: Adds extra underfoot protection and a softer ride when gravel, roots, or rocks demand more cushioning.
• Fully printed upper: Offers a protective yet lightweight layer that resists abrasion and helps keep debris out without adding bulk.
• Vibram Eco-Step outsole: Delivers durable traction and a protective shell around the midsole for confident grip on mixed trail surfaces.
• GORE-TEX waterproof fabric: Shields feet from wind, rain and water while maintaining reasonable breathability for wet-weather runs.

Who It's For

The Fresh Foam X Hierro V8 is best for trail runners and fast hikers who prioritize comfort and cushioning on longer routes, especially in wet or variable conditions where waterproofing matters. It suits those who value a plush midsole and want reliable tread life for repeated miles on technical or mixed-surface trails.

Runners who need a very narrow fit or prefer a minimal, highly responsive racing shoe should look elsewhere, and those who want the absolute lightest trail shoe may find the waterproofing and added stack height add weight compared with stripped-down trail models.

Pros & Cons

Pros

• Exceptional underfoot comfort from the Fresh Foam X cushioning that stays supportive over long distances.
• Waterproof GORE-TEX keeps feet dry without completely sacrificing breathability for wet-weather use.
• Durable Vibram outsole provides dependable grip and long-lasting tread life on rough trails.
• Protective printed upper balances durability and low weight for trail abuse.

Cons

• Fit is reported as mixed by customers; some find the shoe runs small, so trying before committing is advised.
• Grip receives mixed feedback in certain conditions, so extremely technical slippery rock sections may reveal limits versus more aggressive lug patterns.

Frequently Asked Questions

Are these shoes waterproof?
The Hierro V8 uses GORE-TEX fabric, so it will protect feet from rain and puddles while still allowing some breathability.

Do they run true to size?
Customer feedback is mixed; some report true-to-size fit while others find them a bit small, so sizing up may be necessary for wider feet.

Is the outsole reliable on technical trails?
The Vibram Eco-Step outsole offers durable traction for most mixed trails, but very slippery technical rock may expose limitations compared with more aggressive lug designs.
