FAQs

Are these shoes waterproof?

The Fresh Foam X Hierro v9 features a breathable knitted upper that is not fully waterproof. While it offers some protection against light moisture and debris, they are not designed for deep water crossings or heavy rain.

How do I know if I have the right size?

Ensure there is about a thumb's width of space between your longest toe and the end of the shoe when standing. The heel should feel secure without slipping. Refer to New Balance's sizing chart for precise measurements.

Can I use these for road running?

While the Fresh Foam X cushioning provides comfort, the aggressive Vibram® outsole with deep lugs is optimized for trail terrain. They will function on roads but may wear faster and feel less efficient than a dedicated road running shoe.

How often should I replace my trail running shoes?

Trail running shoes typically last between 300-500 miles, depending on terrain and usage. Look for signs of wear, such as flattened cushioning, worn-out tread, or loss of structural integrity.

What is the main difference from previous Hierro models?

The v9 model features a renewed Vibram® outsole tread pattern with deeper lugs for enhanced grip and a refined Fresh Foam X cushioning for an optimal balance of comfort and stability on challenging terrain.

Is the upper material durable?

Yes, the knitted upper is designed for durability on trails while remaining breathable. It's engineered to withstand abrasion from rocks and roots.

Troubleshooting

Reduced grip on wet surfaces

Ensure the Vibram® outsole is clean. Accumulated mud or debris can reduce traction. For extremely wet conditions, consider slower descents or alternative footwear if available.

Discomfort or rubbing

Check lacing to ensure a secure but not overly tight fit. Break in the shoes gradually on shorter runs. Ensure you have the correct size by consulting the sizing guide.

Debris entering the shoe

Ensure the gusseted tongue is positioned correctly. For very dusty or debris-heavy trails, consider wearing gaiters over the shoes.

Pros and Cons

Pros

  • Excellent grip on technical trails due to the Vibram® outsole.
  • Comfortable cushioning for long-distance trail running.
  • Protective upper design guards against trail debris.
  • Durable construction suitable for rugged environments.

Cons

  • May not suit runners who prefer a very minimalist feel.
  • The knitted upper, while breathable, might offer less waterproof protection.
  • Sizing can be a consideration; trying them on or checking reviews is recommended.

Setup, Compatibility & Care Instructions

Setup: These trainers are ready to use right out of the box. Ensure you have the correct size for optimal comfort and performance.

Compatibility: Designed for men's adult foot sizes, specifically suitable for trail running and hiking activities.

Care:

  1. Cleaning: After runs, brush off loose dirt and debris. For a deeper clean, use a damp cloth or a soft brush with cold water. Avoid machine washing or harsh detergents, as this can damage the materials.
  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 deform the shoe.
  3. Storage: Store in a cool, dry place when not in use.
