Nike Air Zoom Alphafly NEXT% 2 'Prototype' - White - Trainers - UK 10

The Atomknit 2.0 upper is designed to improve breathability, especially around the toes, and provides enhanced containment for the forefoot, ensuring a secure fit during high-intensity running.

While comfortable, their specialized design and advanced technology are optimized for running performance. For everyday walking, a more casual shoe might be more suitable for long-term comfort and to preserve the performance features of these trainers.

The carbon fiber plate provides a stiff structure that works with the foam to create a propulsive, forward-rolling sensation, helping to improve running economy and efficiency.

The lifespan depends heavily on usage frequency, intensity, and surface. For racing and high-performance training, they are typically used for a specific mileage range (e.g., 200-400 miles) before performance may gradually decrease.

Yes, the rubber sole provides traction, but it's always advisable to exercise caution on wet surfaces. The upper material is not designed to be fully waterproof.

Prototypes may feature slight variations or early iterations of design elements tested before mass production. Functionally, they are intended to represent the performance characteristics of the final product.

Nike running shoes typically run true to size. It's recommended to consult Nike's official size guide and consider trying them on if possible, especially since performance shoes often have a snugger fit.

The Atomknit 2.0 upper is designed for a snug fit. Loosen the laces and ensure your foot is positioned correctly. With wear, the material may offer a slight give.

The rubber sole is optimized for dry and slightly damp conditions. For very wet or slippery surfaces, exercise caution. Ensure the sole is clean of any debris that might impede grip.

These shoes have a distinct feel due to the carbon plate and foam. Allow a break-in period of a few shorter runs to adapt to the unique geometry and responsive cushioning.
