Extended Product Information

FAQs

Is this shoe suitable for trail running?

No, it is primarily designed for road and paved surfaces. It lacks the aggressive lug depth and protective plates required for technical trails.

How should I clean the white Flyknit upper?

Use a soft-bristled brush or a cloth with mild, soapy water. Gently blot stains rather than rubbing vigorously to avoid damaging the knit fibers.

Does this shoe provide stability?

Yes, it is built with a supportive geometry and secure lockdown features that offer a stable platform for neutral runners.

Can I use these for gym workouts?

While excellent for running, the high-cushion stack height may feel less stable for heavy weightlifting where a flat, firm surface is preferred.

How often should I replace these trainers?

Generally, running shoes should be replaced every 300 to 500 miles, depending on your running surface and individual wear patterns.

Troubleshooting

Feeling discomfort in the arch area

Adjust the tightness of the laces across the midfoot to ensure the lockdown cables are not applying excessive pressure.

Foot slipping inside the shoe

Ensure the shoe is tied using the top eyelet to create a runner's loop, which secures the heel more firmly.

Pros and Cons

Pros

  • Excellent responsive cushioning for long runs
  • Breathable Flyknit material keeps feet cool
  • Secure fit helps prevent unwanted movement
  • Durable outsole performs well on road surfaces

Cons

  • Not intended for technical trail running
  • Design focuses on support rather than lightweight racing speed
  • Requires proper sizing for optimal lockdown

Setup, Compatibility & Care

To ensure the longevity of your trainers, follow these maintenance guidelines:

  1. Sizing: These shoes are true to size; ensure you have a thumbnail's width of space at the front for proper movement.
  2. Lacing: Use the integrated eyelets to adjust the tension of the midfoot lockdown to your personal preference.
  3. Cleaning: Gently wipe the Flyknit material with a damp cloth and mild soap. Avoid machine washing or drying, as high heat can damage the foam and fabric structure.
  4. Drying: Air dry naturally away from direct sunlight or heaters to prevent material degradation.
