Nike Air Zoom Alphafly Next% - Green - Black - UK 11

The primary benefit is enhanced running economy and energy return, designed to help runners achieve faster times with less perceived effort, largely due to the combination of ZoomX foam, Air Zoom pods, and the carbon fiber plate.

While comfortable, the Alphafly Next% is optimized for racing. Its advanced technology and aggressive design are best reserved for race days and specific speed workouts to preserve its performance characteristics and longevity.

Clean them using a soft brush or damp cloth to remove dirt. Allow them to air dry naturally away from direct heat. Avoid machine washing or harsh chemicals.

ZoomX is Nike's lightest and most responsive foam. It provides exceptional energy return and cushioning, helping to reduce fatigue over longer distances.

The full-length carbon fiber plate provides stiffness for propulsion but is designed to work with the foam and rocker geometry to create a smooth, forward-rolling sensation rather than a rigid feel.

AtomKnit is an engineered knit material used for the upper, offering an ultra-lightweight, breathable, and foot-conforming fit that minimizes water absorption.

This specific variant is available in UK size 11. Other sizes are available across different listings of the Nike Air Zoom Alphafly Next% model.

This can sometimes occur due to air trapped in the Zoom Air units or friction between the shoe's components. It often resolves with continued use or may be a minor characteristic of the shoe.

Ensure laces are tied appropriately for a secure but not overly tight fit. If the issue persists, consider if this specific size is correct for your foot. Different models or even variants within the same model can have slight fit variations.

The ZoomX foam and Air Zoom pods are designed for peak performance. Responsiveness may naturally decrease slightly with very high mileage. Ensure the shoes are used primarily for intended purposes (racing/speed work) to maximize their lifespan and performance.
