The New Balance Fresh Foam X Hierro v9 is engineered for ultra trail runners seeking a balance of lightweight design, superior cushioning, and reliable stability on adventurous terrain. While optimized for rugged trails, its comprehensive feature set, including dual-density Fresh Foam X cushioning and a high-traction Vibram Eco Step outsole, ensures confident and comfortable performance. However, as with any specialized trail shoe, its aggressive grip might feel less suited for extended road use.
Fresh Foam X Midsole: Features a dual-density construction with a softer top layer for plush comfort and a firmer layer for enhanced stability, providing a balanced ride on varied surfaces.
Vibram Eco Step Outsole with Traction Lug: Redesigned with deeper 6mm lugs (0.5mm longer than previous versions) and cut-out sections to reduce weight and improve foam displacement, offering superior grip and traction on challenging trails.
Protective Lightweight Mesh Upper: Crafted with strategically placed overlays in high abrasion areas, along with a dedicated Toe Protect feature and abrasion-resistant details to shield feet from rocks and debris.
Redesigned Gusseted Tongue: Ensures a secure and comfortable fit while actively helping to prevent loose debris from entering the shoe.
Optimized Stack Height and Heel Offset: A stack height of 42mm in the heel and 38mm in the forefoot, combined with a 4mm heel offset (changed from 8mm), contributes to increased stability and ground control.
Lightweight Design: Weighing in at approximately 294g (for a single shoe, UK 10.5), it reduces fatigue over long distances without compromising protection.
Exceptional cushioning for long-distance comfort thanks to dual-density Fresh Foam X.
Enhanced stability and control on uneven terrain with a balanced midsole and 4mm drop.
Superior multi-directional traction provided by the revamped Vibram Eco Step outsole with deep 6mm lugs.
Robust protection against trail hazards from the durable mesh upper, overlays, and Toe Protect feature.
Lightweight construction (294g) designed for sustained performance without added bulk.
Secure and comfortable fit that keeps debris out, thanks to the gusseted tongue.
Aggressive outsole lugs, while excellent for trails, may wear faster or feel less comfortable on hard-packed roads.
Info needed: Specific break-in period might be required for optimal comfort due to robust construction.
Info needed: Breathability vs. water resistance balance with the knit upper for extremely wet conditions.
Info needed: May not be ideal for runners who prefer a higher heel-to-toe drop.

The New Balance Fresh Foam X Hierro v9 is purpose-built for the demands of ultra trail running and navigating adventurous, technical terrain. Its performance shines in scenarios where varied surfaces, steep ascents, and rocky descents are commonplace. The dual-density Fresh Foam X midsole delivers a plush feel during initial impact, absorbing shock effectively over long distances, while the firmer layer beneath provides the necessary stability to prevent ankle rolls on uneven ground. For example, when tackling a long, technical descent, runners will appreciate the controlled cushioning and the increased stability offered by the 4mm heel offset, which helps maintain a more natural and secure foot placement.
The Vibram Eco Step outsole, with its deeper 6mm Traction Lugs and revamped pattern, offers tenacious grip across a spectrum of trail conditions – from loose gravel and muddy sections to wet roots and rocky outcrops. Imagine navigating a switchback on a muddy incline; the aggressive lugs dig in, providing reliable propulsion and preventing slippage. The strategic cut-outs in the outsole contribute to a lighter overall shoe, ensuring that responsiveness isn't sacrificed for durability.
Protection is paramount on the trails, and the Hierro v9 delivers. The lightweight mesh upper with strategically placed overlays, along with the Toe Protect feature, acts as a shield against sharp rocks, branches, and other debris that can cause injury. The redesigned gusseted tongue is particularly effective at preventing small stones or sand from entering the shoe, a common nuisance during long trail runs, allowing runners to focus on their stride rather than stopping to empty their shoes. This shoe is an ideal choice for runners training for or competing in long-distance trail races where comfort, protection, and reliable traction are critical for success.
Getting started with your New Balance Fresh Foam X Hierro v9 is straightforward:
Lacing: Ensure the laces are securely tied to provide a snug, comfortable fit without being too tight. The gusseted tongue should sit flush against your foot to prevent debris entry.
Initial Wear: Wear the shoes for short periods initially to allow your feet to adapt to the new cushioning and fit, especially if you are transitioning from a different shoe type or heel drop.
These shoes are designed primarily for:
Terrain: Ultra trail running, technical trails, varied off-road surfaces including dirt, gravel, mud, and rocky terrain.
Runner Type: Ideal for neutral runners seeking a highly cushioned and protective shoe for long distances.
Conditions: Performs well in dry to moderately wet trail conditions. (Note: For extremely wet or cold conditions, consider models with GORE-TEX variants if available for enhanced water resistance).
Proper care will extend the life and performance of your Hierro v9 shoes:
Cleaning: After trail runs, remove excess dirt and mud using a soft brush or cloth. For deeper cleaning, wipe down the upper and outsole with a damp cloth and mild soap. Avoid harsh detergents.
Drying: Allow shoes to air dry naturally at room temperature. Do not use direct heat sources like radiators or tumble dryers, as this can damage materials and adhesives. You can stuff them with newspaper to absorb moisture and maintain shape.
Storage: Store your shoes in a cool, dry place away from direct sunlight.
Avoid Machine Washing: Machine washing can compromise the structural integrity and materials of the shoes.
