Full details

FAQs

Are these shoes suitable for marathon running?

While the Fresh Foam X cushioning offers comfort, these shoes are specifically designed with aggressive trail features. For road marathons, a shoe optimized for that surface might be more suitable. They are excellent for trail ultras or long-distance trail training.

How do I know if this is the right size for me?

Refer to the sizing chart for New Balance adult male footwear. It is recommended to measure your foot length and compare it to the UK sizing guide. Trying them on if possible is always the best method.

Can I wear these shoes in wet conditions?

Yes, the Vibram® outsole provides excellent traction, and the materials offer some protection. However, they are not waterproof. For very wet conditions, consider waterproof socks or trail running shoes with a waterproof membrane.

What is the main difference between the Hierro v9 and previous versions?

The v9 features a revamped Vibram® outsole tread pattern with deeper lugs for improved traction and a modified Fresh Foam X cushioning for enhanced stability and comfort. The upper has also been refined for better breathability and debris protection.

How often should I replace my trail running shoes?

Trail running shoes typically last between 300-500 miles (500-800 km). Signs that replacement is needed include worn-out tread, diminished cushioning, or increased foot fatigue during runs.

Are these shoes available in other colors?

Yes, the Fresh Foam X Hierro v9 series is available in various colorways. Please check with specific retailers for current availability, as the 'Green/Black' color is one of several options.

Troubleshooting

Reduced grip on wet surfaces

Ensure the Vibram® outsole is clean. Over time, packed-in mud or debris can affect grip. Rinse the outsole with water and allow it to dry.

Discomfort or rubbing

Verify the correct size and width. Ensure socks are appropriate for trail running. Break in the shoes gradually on shorter runs before attempting long distances.

Cushioning feels too firm

The dual-density cushioning is designed for stability. The 'firmer' layer provides this support. The cushioning will adapt slightly with more wear, but the inherent stability will remain.

Debris entering the shoe

Ensure the gusseted tongue is properly aligned. For very fine debris, consider using gaiters in conjunction with the shoes.

Pros and Cons

Cons

  • May feel less responsive on paved or road surfaces compared to trail-specific use.

Setup, Compatibility & Care

Setup: These trainers are ready to wear straight out of the box. No specific setup is required. Ensure they fit correctly before their first use on the trail.

Compatibility: Designed for male adult foot sizes. The series is optimized for trail running and hiking over mixed terrain.

Care Instructions:

  1. Cleaning: Remove loose dirt and mud with a soft brush. For a deeper clean, use a damp cloth and mild soap. Avoid machine washing or harsh detergents, as this can damage the materials and cushioning.
  2. Drying: Allow the shoes to air dry naturally at room temperature. Do not place them near direct heat sources like radiators or in direct sunlight, as this can cause the materials to warp or degrade.
  3. Storage: Store in a cool, dry place when not in use. Ensure they are clean and completely dry before storing to prevent mildew or odors.
