Product Information

Full details

The Nike ReactX Infinity 4 trainers are designed for adult male runners seeking a balance of high-level comfort and responsive support for daily training sessions. Utilizing Nike's proprietary ReactX foam technology, these shoes deliver significant energy return with every stride, making them an ideal choice for neutral runners who prioritize joint protection. While they offer excellent cushioning, users should note that the performance-oriented foam may feel firmer than traditional lifestyle sneakers until fully broken in during initial runs.

FAQs

Are these shoes suitable for flat feet?

The ReactX Infinity 4 provides neutral support. If you require specific arch correction, consult with a podiatrist regarding the use of custom orthotic insoles.

Can I use these for marathon training?

Yes, the ReactX foam is specifically engineered for long-distance comfort, making them a great choice for high-mileage training.

Is the sizing true to fit?

Yes, these generally follow standard UK sizing conventions for Nike running footwear.

How often should I replace these trainers?

It is generally recommended to replace running shoes every 300-500 miles, depending on your running style and surface conditions.

Are they waterproof?

No, the upper material is designed for maximum breathability rather than water resistance.

Troubleshooting

Feeling of stiffness in the midsole

The ReactX foam requires a short break-in period of approximately 20-30 miles to fully adapt to your foot strike.

Surface stains on the white upper

Gently spot clean with a damp cloth and mild soap; avoid harsh chemical cleaners that may discolor the fabric.

Slippage during wet conditions

Ensure the outsole treads are clear of debris, as packed mud or gravel can reduce the rubber grip on smooth surfaces.

Pros and Cons

Pros

  • High energy return for efficient daily running
  • Balanced support system for neutral foot strikes
  • Breathable material keeps feet cool during extended use
  • Clean, professional design suitable for varied settings

Cons

  • Requires a short break-in period for the foam to reach peak comfort

  • Not intended for heavy trail running or off-road use

Setup, Compatibility & Care

To ensure the longest lifespan for your Nike ReactX Infinity 4 trainers, always loosen the laces fully before putting the shoe on to prevent damage to the heel counter. These are standard road running shoes and perform best on paved or synthetic surfaces. For care, avoid machine washing or drying, as high heat can degrade the foam properties and adhesive integrity. Instead, clean the exterior using a soft brush, warm water, and a mild detergent. Allow the shoes to air dry naturally away from direct sunlight or extreme heat sources.
