FAQs
Are these shoes suitable for flat feet?
Yes, the ReactX Infinity 4 provides structured support that can be beneficial for runners who need extra stability.
Can I use these for speed workouts?
While durable and responsive, they are designed primarily for distance and recovery, not for track-based speed work.
How do I know if the 8.5 UK size is right for me?
Nike trainers generally fit true to size. If you have worn other Nike running shoes in the past, your usual size should be accurate.
Is the material breathable?
The upper is constructed with engineered materials to balance security with breathability for consistent comfort.
Do I need to wear specific socks with these?
For optimal performance, moisture-wicking synthetic or merino wool running socks are recommended to prevent friction.
Troubleshooting
Feeling pressure points on the top of the foot
Adjust the lacing tension; try a 'window lacing' technique to relieve pressure over the midfoot area.
Outer sole appears to be wearing down unevenly
Check your gait or foot strike; you may benefit from a professional gait analysis to ensure the shoe type matches your mechanics.

Setup, Compatibility & Care
To ensure the longevity of your Nike ReactX Infinity 4 trainers, follow these basic care steps:
- Breaking In: Wear them for short walks before moving to longer runs to allow the foam to adapt to your foot.
- Cleaning: Hand wash using a soft brush and mild soap; avoid harsh chemicals that can degrade the foam.
- Drying: Air dry only in a shaded, well-ventilated area. Do not place them near radiators or in a tumble dryer, as heat can warp the cushioning.
- Rotation: If running daily, rotate with another pair of trainers to allow the foam to fully decompress and recover between sessions.
