Nike Air Zoom Alphafly NEXT% 2 Prototype - White - UK 10.5

ZoomX foam provides Nike's lightest and most energetic foam, offering excellent cushioning and a high degree of energy return to help runners feel faster and fresher.

The carbon fiber plate is designed to provide a propulsive feel, creating a stiff lever that helps to stabilize the foam and deliver a snappy, forward-moving sensation during the gait cycle.

While durable, the Alphafly NEXT% 2 Prototype is optimized for speed. For everyday mileage, a shoe with less aggressive geometry and a different foam setup might be more comfortable and suitable for long-term wear.

The Atomknit 2.0 upper can be gently cleaned with a damp cloth and mild soap. Avoid harsh scrubbing or machine washing to preserve its structure and breathability.

Prototype versions often signify early releases or specific colorways. The core technology and performance features remain consistent with the standard model unless otherwise specified.

These shoes are primarily designed for road running. They perform best on pavement, asphalt, and standard running tracks.

The lifespan of the cushioning depends on mileage, running surface, and individual running mechanics. For optimal performance, many runners reserve their Alphaflys for key races and tempo sessions to extend their effective lifespan.

Ensure laces are loosened before putting on the shoes. Adjust lacing to your foot shape, perhaps skipping eyelets or using a different lacing pattern. Allow for a break-in period of a few runs.

Ensure the shoes are properly broken in. Check for any debris trapped in the outsole or midsole that might be affecting performance. Note that foam and air pods can naturally degrade over very high mileage.

Avoid using the shoes for activities other than running on appropriate surfaces. Ensure proper cleaning and drying techniques are followed. Inspect for any manufacturing defects if wear appears unusually early.
