FAQs

Are these shoes suitable for flat feet?

The Infinity Run 4 series is built with a focus on stability, which often provides good support for runners with mild pronation or flat feet.

Can I use these for marathon training?

Yes, the ReactX cushioning is specifically engineered for high-mileage comfort, making them an excellent candidate for marathon training blocks.

Is the sizing true to fit?

Nike trainers generally fit true to size, but since this model offers a structured fit, consider your preference for sock thickness.

How long should the foam last?

Most runners find that the midsole cushioning remains effective for approximately 400 to 500 miles, depending on running surface and gait.

Are these waterproof?

No, the performance mesh upper is designed for breathability and will allow water to pass through if you step in puddles.

Troubleshooting

Feeling discomfort in the arch area

Try re-lacing the shoe using the secondary eyelets to adjust the lockdown tension across the top of the foot.

Excessive dirt on the mesh upper

Spot clean with lukewarm water and a mild detergent; avoid soaking the shoe entirely to preserve the glue integrity.

Pros and Cons

Pros

  • Superior responsive cushioning for joint protection
  • Highly durable outsole for long-term road running
  • Breathable material keeps feet cool
  • Excellent stability for daily high-mileage training

Cons

  • Not intended for pure speed or track racing
  • Larger sizes may feel bulkier than lightweight racing flats
  • Limited to specific road-oriented use

Setup, Compatibility & Care

To ensure your trainers last, rotate them with another pair to allow the foam to decompress between runs. When cleaning, use a soft-bristled brush to remove dried mud and wipe the upper with a damp cloth and mild soap; avoid machine washing or using high-heat dryers as this can damage the foam properties and structural adhesives. Ensure your laces are tensioned comfortably across the midfoot to leverage the built-in support features fully.
