FAQs

Are these shoes suitable for road running?

While wearable, they are specifically engineered for trail running. The outsole pattern is optimized for dirt and uneven terrain, which may wear out prematurely on concrete or asphalt.

How do I determine the correct fit for this model?

These trainers follow standard adult UK sizing. We recommend checking your current Nike footwear size as a baseline for the best fit.

Can I put these shoes in the washing machine?

No, machine washing is not recommended. It can compromise the adhesive and the specific properties of the ZoomX foam.

What is the primary benefit of the ZoomX foam?

The primary benefit is maximum energy return, which helps reduce the physical effort required to push off the ground during your run.

Are these shoes water-resistant?

The construction is durable for outdoor use, but they are not categorized as waterproof. They are designed to be breathable, which means water can penetrate if submerged.

Troubleshooting

Foam feels less responsive over time

Ensure the shoes are given at least 24 hours to recover between intensive runs to allow the foam to decompress.

Accumulation of debris inside the shoe

Check that the laces are securely tightened and consider using gaiters if running on particularly sandy or rocky trails.

Pros and Cons

Pros

  • Excellent energy return from ZoomX foam
  • High-visibility design for trail safety
  • Durable construction suitable for harsh terrain
  • Comfortable for long-duration running

Cons

  • Not intended for paved road surfaces
  • Bright colourway may show dirt more easily
  • Specialized fit may require break-in period

Setup, Compatibility & Care

To ensure the longevity of your trainers, it is essential to follow basic care guidelines. After running on muddy or wet trails, remove the insoles and allow the shoes to air dry naturally away from direct heat sources, such as radiators, which can degrade the foam. Use a soft-bristled brush to remove dried dirt from the outsole after each session. For cleaning the upper, wipe with a damp cloth and mild soap; avoid machine washing as this may damage the structural integrity of the ZoomX cushioning. Store the shoes in a cool, dry place to prevent material breakdown.
