Product Information

Full details

The Nike React Infinity Run Flyknit 4 is designed for runners who prioritize support and maximum cushioning, making it an excellent choice for daily training and long-distance comfort. Featuring advanced React foam technology, these trainers provide a highly responsive ride while maintaining a lightweight feel; however, runners seeking a minimalist or 'barefoot' sensation may find the extra cushioning too plush for their specific training goals.

FAQs

Can I use these for marathon training?

Yes, the React foam is specifically engineered for high-mileage runs, providing the support and cushioning needed for marathon training.

Are these suitable for trail running?

These shoes are optimized for road and gym use. They do not feature the aggressive tread or rock protection required for technical trail running.

How should I store these trainers?

Store them in a cool, dry area away from direct sunlight, which can cause the materials to yellow or become brittle over time.

Are they true to size?

The Flyknit upper offers a snug, sock-like fit. Many runners find them true to size, but measuring your foot accurately is recommended to ensure a perfect fit.

How do I know when it is time to replace them?

Generally, running shoes should be replaced every 300 to 500 miles, or sooner if you notice visible compression of the foam or wear on the outsole.

Troubleshooting

Feeling of slipping or heel instability

Ensure you are using the correct lacing technique to lock the midfoot in place, or consider a thicker performance sock to take up excess volume.

Build-up of dirt on the white or light-colored foam

Spot clean the midsole using a damp cloth and a small amount of mild detergent, wiping gently to avoid damaging the foam surface.

Upper material losing its shape

Avoid over-tightening the laces; store the shoes in a cool, dry place out of direct sunlight when not in use.

Pros and Cons

Pros

  • Superior impact cushioning for joint comfort
  • Breathable Flyknit material prevents overheating
  • Highly responsive energy return during strides
  • Versatile design suitable for both gym and road running

Cons

  • Plush foam may feel too soft for those preferring firm ground contact
  • Sizing requires precise measurement to ensure the correct locked-in fit
  • Flyknit material may offer less structure than traditional mesh trainers

Setup, Compatibility & Care

To ensure the best performance from your trainers, begin by measuring your foot length from heel to toe. Because of the stretchy nature of the Flyknit upper, achieving the correct size is essential for avoiding slippage. For maintenance, it is recommended to keep the shoes away from heavy mud or water-saturated environments, as this can degrade the foam integrity and stain the fabric. To clean the shoes, use a soft-bristled brush or a damp cloth with mild, non-bleach soap; never place them in a washing machine or dryer, as high heat can compromise the foam and adhesive components.
