FAQs

Is this shoe suitable for flat feet?

The ReactX Infinity Run 4 offers supportive features that can be beneficial for runners who need a stable platform, though personal biomechanics vary.

Can I use these for trail running?

These shoes are designed primarily for road surfaces. The outsole pattern may not provide sufficient grip on technical or loose trail terrain.

How often should I replace these trainers?

General guidance suggests replacing running shoes every 300-500 miles, depending on your weight, running surface, and individual wear patterns.

Does the ReactX foam degrade quickly?

ReactX is engineered for durability and longevity, maintaining its responsiveness better over time than standard EVA foams.

Are these shoes machine washable?

No, it is highly recommended to hand clean them using a soft cloth or brush to prevent damaging the technical materials and adhesives.

Is the sizing true to fit?

The Nike ReactX Infinity Run 4 generally follows standard athletic sizing; however, always refer to your personal fit preference if you prefer extra room in the toe box.

Troubleshooting

Shoes feel tight after a long run

Feet naturally swell during exercise. Ensure your laces are adjusted mid-run to accommodate this expansion without compromising security.

Outsole loses grip on wet surfaces

Clean the rubber sole regularly to remove debris or dried mud, as trapped particles can decrease friction on smooth or wet roads.

Visible creases in the foam midsole

This is a normal characteristic of performance foam as it compresses and expands; it does not indicate a structural failure of the shoe.

Pros and Cons

Pros

  • Advanced ReactX foam provides superior energy return.
  • Excellent stability features for consistent stride support.
  • Breathable upper material maintains comfort over long durations.
  • Durable construction suitable for high-mileage training.
  • Striking yellow and black colorway offers high visibility.

Cons

  • Bold color scheme may not suit every runner's personal style.
  • Designed primarily for road running, not ideal for technical trail terrain.
  • Sizing can feel different due to the supportive structure compared to neutral racing flats.

Setup, Compatibility & Care

To ensure the longevity of your Nike ReactX Infinity Run 4 trainers, it is recommended to rotate them with other shoes to allow the foam to decompress. When cleaning, avoid using harsh chemicals or the washing machine. Instead, gently scrub the outsole with a soft brush and warm soapy water. For the upper, use a damp cloth to spot clean any dirt or debris. Ensure you select the correct UK size, such as the UK 12.5, to prevent friction and ensure the support technology is positioned correctly against your arch.
