Extended Product Information

FAQs

Can I use these for marathon running?

Yes, the responsive React foam is designed for long-distance comfort, provided the shoe fits your specific foot shape well.

Are these shoes water-resistant?

The Flyknit upper is breathable and permeable, so they are not waterproof and are best suited for dry weather.

How do I know if this size fits?

The shoe should feel snug and secure without causing numbness or pinching; ensure you have about a thumb's width of space at the toes.

Do I need to wear socks with these?

While the interior is designed for comfort, we recommend wearing moisture-wicking running socks to prevent chafing.

Can I replace the insole?

The insole is designed to be integrated into the shoe's cushioning system; we recommend using the factory-provided insole for the intended performance.

Are these suitable for gym workouts?

They are excellent for treadmill runs and general cardio, though they lack the lateral support needed for heavy weightlifting.

Troubleshooting

Difficulty sliding foot into the shoe

Ensure you are pulling firmly on the heel tab to fully expand the collar before entry.

Feeling too much pressure across the midfoot

Allow the Flyknit material time to stretch naturally through a few short walks before extended running.

Outsole debris buildup

Use a soft brush or a blunt tool to gently clear small stones or dirt trapped in the outsole treads.

Pros and Cons

Pros

  • Effortless slip-on functionality
  • Highly responsive cushioning for distance running
  • Breathable Flyknit material keeps feet cool
  • Supportive heel design prevents slipping

Cons

  • No traditional laces for customized tension adjustment
  • May feel too snug for users with exceptionally wide feet
  • Not suitable for technical trail terrain

Setup, Compatibility & Care

To ensure the best experience, pull the heel tab to widen the opening before sliding your foot in; the snug nature of the Flyknit upper is intentional to ensure security while running. As a technical trainer, it is compatible with standard running socks. To maintain the shoes, avoid machine washing; instead, spot clean with a soft-bristled brush, mild soap, and cold water. Let the shoes air dry naturally away from direct heat sources to preserve the integrity of the React foam and the shape of the TPU heel counter.
