Crusher Sonic Knit sneakers - White - UK 11

These trainers are best suited for adult runners, particularly those focusing on distance running, who prioritize joint protection and seek good energy return. They are also suitable for general athletic activities.

The cushioning features two distinct densities. A firmer density provides support and stability, while a softer density offers superior shock absorption and energy return upon impact.

The technical mesh upper is designed for breathability and a flexible fit. While generally durable for running purposes, it's important to follow care instructions to maintain its integrity.

While comfortable and stable, they are primarily designed for running. For sports requiring lateral support or specific traction (like court sports or trail running), a specialized shoe might be more appropriate.

Ensure there is about a thumb's width of space between your longest toe and the front of the shoe when standing. The heel should feel secure without slipping, and the midfoot should be snug but not constricting.

The reflective details are designed to enhance visibility when illuminated by light sources in low-light conditions. They increase safety but do not guarantee visibility in complete darkness.

The sole incorporates dual-density cushioning and PU inserts for stability, designed to provide a blend of shock absorption and energy return.

Adjust the lacing system to find a secure yet comfortable fit. If the issue persists, consider if this specific size is correct for your foot shape or if a different model might be more suitable.

The cushioning materials naturally compress with use. Ensure the shoes are clean and dry; significant loss of cushioning may indicate the end of their optimal performance life.

Check lacing and ensure the technical mesh upper is properly aligned with your foot. Consider using specialized running socks. If discomfort persists, the shoe's specific support may not be ideal for your gait.

This can sometimes occur due to friction between internal components or moisture. Ensure the shoes are completely dry. If it persists, it may be a manufacturing anomaly.
