Full details
The Nike React Infinity Run Flyknit 2 is designed for adult male runners seeking a balance of soft cushioning and injury prevention during high-mileage training.

Extended Product Information
FAQs
Is this shoe suitable for trail running?
These are primarily designed for road and pavement use; the foam is not engineered for sharp rocks or technical terrain.
How long should the foam last?
Typically, the cushioning remains effective for 300 to 500 miles, depending on your running style and weight.
Can I put these in the washing machine?
It is recommended to hand wash only, as machine washing and drying can damage the adhesive and the structural integrity of the Flyknit.
Are these shoes true to size?
The fit is generally consistent with standard Nike sizing, though the Flyknit upper offers a snug, sock-like feel.
Why does the shoe feel stiff initially?
The stability elements in the sole require a few runs to flex naturally and match your foot's gait cycle.
Troubleshooting
Heel slippage during runs
Use the runner's loop (heel lock) lacing technique to increase tension around the ankle collar.
Midfoot tightness
Loosen the lacing system, specifically the eyelets connected to the Flywire cables, to redistribute pressure.

Setup, Compatibility & Care
To ensure the best performance, secure the laces using the Flywire-connected eyelets to achieve a snug midfoot fit before your first run. The shoes are compatible with standard running socks; avoid thick hiking socks, which may alter the intended fit.
To care for your shoes, remove surface dirt with a soft brush after each run. If the trainers become wet, stuff them with newspaper to absorb moisture and allow them to air dry away from direct heat sources, as extreme heat can degrade the foam’s responsiveness over time.
