FAQs
What is the main advantage of the Zoom Air units?
The two Zoom Air units in the forefoot provide exceptional responsiveness and energy return, helping to propel you forward with each step and reduce fatigue.
Is the carbon fiber plate noticeable during a run?
Yes, the carbon fiber plate works in conjunction with the foam and Zoom Air units to create a stiff, propulsive sensation that helps you transition quickly through your stride.
Who is this shoe best suited for?
These shoes are best suited for competitive runners aiming for peak performance on race day, particularly for distances from 5K to marathons. They are designed for speed and efficiency.
How does the Atomknit upper differ from traditional mesh?
Atomknit is a lighter, more breathable material that offers a sock-like fit, conforming to the foot while providing strategic support and ventilation.
Can I use these for everyday training?
While durable, these shoes are highly specialized for performance. It's generally recommended to save them for key workouts and races to preserve their advanced features and prolong their lifespan. Everyday training might be better suited for more robust, less performance-oriented shoes.
What does 'Next%' signify?
The 'Next%' in the name refers to Nike's pursuit of the next percentage of improvement in running performance, highlighting the shoe's focus on maximizing speed and efficiency.
How do I choose the right size?
Given the snug, performance-oriented fit, it's advisable to try them on if possible. Many runners find they wear the same size as their other Nike performance trainers, but some may opt for a half-size larger for added comfort during longer runs.
Troubleshooting
Shoe feels too tight or uncomfortable
Loosen the laces and re-tie them, ensuring even pressure. If the issue persists, consider if a different size or width might be more suitable, or if an adjustment period is needed.
Reduced cushioning or responsiveness over time
The foam and air units may compress with significant use. Ensure the shoes are clean and dry, as debris can sometimes affect performance. For persistent issues, it may indicate the shoe has reached the end of its optimal lifespan.
Traction seems poor on wet surfaces
Ensure the outsole is clean from mud or debris. While designed for grip, extreme wet conditions can challenge any outsole. Consider using more caution or alternative footwear if racing in very wet conditions.

Setup, Compatibility & Care
Setup: These shoes are designed to be worn directly out of the box for performance. Ensure a snug but comfortable fit by lacing them appropriately before your run.
Compatibility: The Nike Air Zoom Alphafly Next% is ideal for road running and track competitions. It is not recommended for trail running or extensive cross-training due to its specialized construction.
Care:
- Cleaning: After use, remove excess dirt with a soft brush. For tougher stains, use a damp cloth with mild soap and water. Avoid machine washing or harsh detergents.
- Drying: Allow the shoes to air dry naturally at room temperature. Do not expose them to direct heat sources like radiators or hairdryers, as this can damage the materials.
- Storage: Store in a cool, dry place away from direct sunlight. Using a shoe tree can help maintain their shape.
