Product Information

Full details

The Nike ReactX Infinity Run 4 is designed for male runners seeking a balance of reliable support and responsive cushioning, making it an excellent choice for daily mileage and recovery runs. Featuring the innovative ReactX foam technology, this trainer delivers a smooth, bouncy ride that helps reduce fatigue during longer sessions. While it excels in stability and comfort, users should note that the bold yellow and black colorway is highly visible, which may not suit those preferring a more subdued or minimalist aesthetic.

FAQs

Are these shoes suitable for flat feet?

Yes, the supportive construction of the ReactX Infinity Run 4 provides a stable platform that works well for various arch types.

Can I use these for marathon training?

Absolutely. These are designed as daily trainers, making them ideal for the repetitive, high-mileage efforts required in marathon preparation.

How often should I replace these trainers?

It is generally recommended to replace running shoes every 300 to 500 miles, depending on your running surface and body weight.

Is the ReactX foam different from standard React foam?

Yes, ReactX foam is an evolution of standard React, providing higher energy return while maintaining the same weight profile.

What is the best way to dry them if they get wet?

Remove the insoles and stuff the shoes with newspaper. Let them air dry in a well-ventilated area away from direct heat sources like radiators.

Troubleshooting

Feeling of slipping at the heel

Try the 'runner's loop' lacing technique to secure the heel more firmly against the back of the shoe.

Dirt buildup on the sole

Use a damp cloth and a soft-bristled brush to gently remove debris from the grooves of the outsole after each run.

Setup, Compatibility & Care

To ensure your Nike ReactX Infinity Run 4 trainers maintain their performance, follow these guidelines:

  1. Fit Check: Ensure the size is correct; the UK 12 provides ample room in the toe box, which is ideal for preventing discomfort during long runs when feet naturally swell.
  2. Break-in Period: While comfortable out of the box, walk in them for a few days to let the foam and upper materials adapt to your foot shape.
  3. Cleaning: Hand wash only using mild soap and a soft brush. Do not machine wash or tumble dry, as high heat can degrade the integrity of the foam cushioning.
  4. Storage: Store in a cool, dry place away from direct sunlight to prevent the vibrant yellow pigments from fading and to preserve the life of the materials.
