Nike Alphafly 3 Trainers - Grey/White - UK 8.5

The Nike Alphafly 3 is designed for adult male athletes who prioritize speed and performance, particularly for competitive running events like marathons and half-marathons.

Refer to the sizing chart and ensure you measure your foot accurately. It is recommended to try them on if possible, as performance footwear fit can be personal. For this model, UK 8.5 is specified.

While durable, the Alphafly 3 is optimized for performance. For everyday mileage and recovery runs, a different shoe with more forgiving cushioning might be more suitable to preserve the advanced technology of the Alphafly 3.

The full-length carbon fiber plate enhances propulsion by providing a stiff lever arm, increasing energy return and promoting a more efficient stride.

It combines responsive foam with Zoom Air units strategically placed to absorb impact and provide a springy, energetic feel with each step.

No, the shoes are designed with breathable materials for ventilation and are not waterproof. They are best suited for dry or moderately wet conditions.

The lifespan varies based on mileage, terrain, and individual running style. For optimal performance, many runners replace their racing shoes every 300-500 miles, but this can differ significantly.

This is common with high-performance shoes. Try wearing them for shorter durations initially and gradually increase mileage. Ensure laces are adjusted correctly, not too tight or too loose.

Ensure the shoes are clean and free of debris, especially in the midsole and outsole areas. Prolonged exposure to extreme temperatures can also affect foam properties.

While designed for grip, extreme wet conditions can reduce traction for any shoe. Exercise caution and reduce speed on slick surfaces. Ensure the outsole is not worn down.
