FAQs
Are these shoes suitable for flat feet?
Yes, the React Infinity Run features stability geometry that offers good support for runners who need extra help maintaining a neutral gait.
Can I use these for gym workouts?
While primarily a running shoe, they are stable enough for light gym activities, though the high-stack foam is not ideal for heavy lifting.
How often should I replace these trainers?
Depending on your running frequency, it is generally recommended to replace them every 500 to 800 kilometers.
Is the material waterproof?
No, the Flyknit upper is highly breathable and will allow water to pass through if you run in heavy rain.
Are these true to size?
The Nike React Infinity Run generally fits true to size, but the knit material can have a snug feel; consider half a size up if you prefer more toe-box volume.
Troubleshooting
Knit upper feels too tight across the midfoot
Try a different lacing technique, such as skipping the eyelet where the pressure occurs to allow more room.
Foam feels stiffer than expected
The React foam may require a break-in period of 30-50 kilometers to soften up and become more flexible.
Heel slippage while running
Use a runner's loop (heel lock lacing) to create a more secure fit around the ankle collar.

Setup, Compatibility & Care
To ensure optimal performance, start by securing the laces to match your preferred level of midfoot lockdown, ensuring not to overtighten and restrict circulation. For care, keep the Flyknit upper free of mud by wiping it with a damp cloth after runs; avoid machine washing, which can damage the structural integrity of the knit. If the shoes become soaked, remove the sockliner and stuff the interior with newspaper to draw out moisture, letting them air dry away from direct heat sources like radiators, which can warp the foam midsole.
