ASICS Novablast 4 - Black Graphite Grey - Trainers - UK 12

The Novablast 4 is best suited for adult male runners looking for an energized and responsive shoe for daily training, tempo runs, and even longer distances. It is designed for neutral pronation.

FLYTEFOAM BLAST™ technology provides lightweight cushioning with high energy return, creating a 'bouncy' and propulsive feel that helps make your runs feel more effortless and dynamic.

GUIDESOLE™ technology is a unique sole geometry that helps reduce ankle flexion and creates a smooth, efficient forward-rolling motion, conserving energy during your stride.

Yes, due to their lightweight nature and high energy return, the Novablast 4 can be effectively used for racing, particularly for distances up to a half marathon or for faster training sessions.

Clean them with a soft brush to remove loose dirt. For a deeper clean, use a damp cloth and mild soap. Always air dry them away from direct heat.

While they can handle light trails due to their durable outsole, they are primarily designed for road running. For technical or muddy trails, specialized trail running shoes are recommended.

The Novablast 4 features an updated midsole foam compound for enhanced energy return and a revised upper for improved comfort and breathability. The geometry has also been refined for a smoother ride and increased stability.

Ensure you have selected the correct UK size. Consider trying a half-size up or down, or exploring options for wider fits if available, as individual foot shapes vary.

The FLYTEFOAM BLAST™ cushioning is designed for longevity, but natural wear and tear can occur. Ensure the shoes are clean and dry; excessive dirt can sometimes affect performance. If performance significantly degrades, it may be time to consider replacement after extensive use.

The outsole provides good traction on dry surfaces. On very wet or slick conditions, reduce speed and exercise caution. The grip is optimized for typical running conditions, not extreme wet surfaces.
