FAQs

What is the main difference between the Alphafly NEXT% 2 and the Prototype version?

The Prototype version features an improved Atomknit 2.0 upper for enhanced breathability and forefoot containment compared to earlier versions. The core technology (ZoomX foam, Zoom Air pods, carbon plate) remains consistent.

Are these shoes suitable for marathon training?

Yes, they are ideal for long runs and race day during marathon training due to their advanced cushioning and energy return, which help mitigate fatigue.

Can I use these shoes for everyday training runs?

While possible, they are optimized for speed and racing. For daily mileage, you might consider a more durable or less aggressive shoe to preserve the advanced features of the Alphafly for key workouts and races.

How do I clean my Nike Air Zoom Alphafly NEXT% 2 Prototype shoes?

Clean with a soft brush for dry dirt and a damp cloth with mild soap for tougher grime. Avoid machine washing and allow them to air dry away from heat.

What is the purpose of the carbon plate in this shoe?

The carbon fiber plate is designed to provide a stable platform for the ZoomX foam and Zoom Air pods, promoting efficient forward propulsion and a smooth transition from heel to toe.

What is the warranty period for these shoes?

Nike typically offers a limited warranty against manufacturing defects. Please refer to Nike's official website or your purchase receipt for specific warranty details, as it can vary by region and retailer.

Are these shoes waterproof?

No, the Atomknit 2.0 upper is designed for breathability, not waterproofing. They will get wet in rain or through puddles.

Troubleshooting

Shoe feels too stiff or unresponsive initially

The shoe may require a break-in period. Gradually increase the mileage in the shoes over a few runs to allow the materials to adapt to your foot and running style.

Upper feels too tight or restrictive

Ensure you have the correct size and width. If the fit is still too snug, try loosening the laces, especially around the midfoot, to create more volume. The Atomknit 2.0 upper is designed for containment but should not cause discomfort.

Reduced cushioning or energy return over time

While durable, the advanced foam and air pods can degrade with excessive use or improper care. Ensure the shoes are cleaned and dried properly after each use and stored correctly to prolong their performance.

Slipping on wet surfaces

The rubber sole provides good traction, but like all athletic shoes, performance can be reduced on very wet or slick surfaces. Run with caution in wet conditions.

Setup, Compatibility & Care

Setup: These are running shoes and require no setup beyond putting them on. Ensure you have the correct fit before your first run.

Compatibility: Designed for road running and track racing. Not recommended for trail running or intense gym workouts.

Care:

  1. Cleaning: After runs, use a soft brush to remove dry dirt. For tougher dirt, use a damp cloth and mild soap. Avoid machine washing or harsh detergents.
  2. Drying: Air dry the shoes away from direct heat sources. Stuffing them with paper can help absorb moisture and maintain shape.
  3. Storage: Store in a cool, dry place. Avoid prolonged exposure to sunlight or extreme temperatures.
