The New Balance Fresh Foam X Hierro v9 is purpose-built for the rigorous demands of ultra trail running and general off-road adventures. Its dual-density Fresh Foam X midsole provides a critical balance, offering soft, plush cushioning for sustained comfort over long distances, while a firmer layer ensures the stability needed to navigate technical terrain. This makes it ideal for varied landscapes, from rocky singletrack to root-laden forest paths.
Long Trail Runs: The increased foam and signature Fresh Foam X comfort absorb impact effectively, reducing fatigue during multi-hour outings.
Technical Terrain: The 4mm drop, combined with the stable midsole, enhances ground feel and control, allowing for confident navigation over uneven surfaces.
Rocky Paths: Toe Protect and abrasion-resistant overlays offer crucial defense against sharp rocks and debris, protecting your feet from impact.
Loose Dirt and Mud: The Vibram Eco Step outsole, with its aggressive 4.5mm Traction Lugs, digs into loose ground, providing reliable grip and preventing slips.
Lacing: Ensure the laces are snug but not overly tight. The gusseted tongue is designed to stay in place, contributing to a secure fit.
Break-In: While comfortable out of the box, it's recommended to wear them for shorter runs or walks before tackling your longest trail adventures to fully adapt to the 4mm drop and shoe's feel.

Terrain: Best suited for varied trail conditions, including technical sections, loose dirt, and rocky paths.
Proper care extends the life and performance of your Hierro v9s:
Cleaning: After a muddy run, gently brush off loose dirt. For deeper cleaning, hand wash with mild soap and cold water. Avoid machine washing or harsh detergents.
Drying: Remove insoles and allow the shoes to air dry naturally at room temperature. Avoid direct heat sources like radiators or sunlight, as this can damage materials.
Storage: Store in a cool, dry place away from direct sunlight. Ensure shoes are completely dry before storing to prevent odor and material degradation.
Inspection: Regularly check the outsole lugs for wear and the upper for any signs of damage to ensure continued optimal performance and safety.
