FAQs
Are these shoes suitable for flat feet?
Yes, the supportive geometry and stable foam base of the React Infinity Run make them suitable for a variety of foot types, including those needing extra stability.
Can I use these for gym workouts?
While primarily a road running trainer, the supportive upper makes them capable for general fitness activities, though they are specifically optimized for forward linear motion.
How often should I replace these trainers?
Generally, performance trainers like these should be replaced every 300 to 500 miles, depending on your running surface and body weight.
Does the Flywire technology need special care?
Avoid pulling excessively hard on the laces, as the Flywire cables are integrated directly into the eyelets and provide structural support.
Are these waterproof?
No, the trainers feature a breathable upper designed for airflow, which means they are not waterproof and may absorb water in heavy rain.
Troubleshooting
Feeling pressure on the top of the foot
Adjust the laces using the 'window' lacing technique to relieve tension on the bridge of the foot while maintaining midfoot security.
Inner heel slipping
Utilize the 'runner's loop' or heel lock lacing method with the top eyelet to secure the heel cup more firmly against the ankle.

Setup, Compatibility & Care
To ensure the longevity of your Nike React Infinity Run trainers, follow these maintenance guidelines:
- Sizing: These shoes are true to size. Ensure you have a thumb-width of space between your longest toe and the front of the shoe.
- Break-in: While comfortable out of the box, wear them for shorter walks or easy jogs before attempting long-distance runs to allow the upper materials to conform to your foot.
- Cleaning: Hand wash with cool water and a mild detergent. Do not machine wash or dry, as high heat can damage the React foam and adhesive bonding.
- Drying: Air dry naturally away from direct sunlight or heat sources like radiators to prevent material warping or yellowing.
