Setup, Compatibility & Care
To ensure the longevity of your New Balance Fresh Foam X Hierro v9, follow these guidelines:
- Sizing: These shoes are sized for standard adult feet. Use the UK sizing conversion to ensure a snug fit with a thumb's width of space at the toes.
- Break-in Period: While comfortable out of the box, wear them for shorter walks before attempting long-distance trail runs to allow the foam to adapt to your gait.
- Cleaning: After muddy runs, remove excess dirt with a soft brush once the shoe has dried. Avoid machine washing or using harsh chemical cleaners, as these can degrade the polyester upper and foam properties.
- Storage: Store in a cool, dry place away from direct sunlight to prevent the foam from prematurely oxidizing or hardening.
