Crusher Sonic Knit sneakers - White - UK 5.5

The dual-density cushioning provides both shock absorption to protect your joints from impact and energy return to help propel you forward with each stride, enhancing running efficiency.

While they can be used for general fitness, their design is primarily optimized for running. For activities requiring significant lateral support, specialized training shoes might be more appropriate.

There should be about a thumb's width of space between your longest toe and the front of the shoe when standing. The shoe should feel snug but not tight, with no excessive pressure points.

No, machine washing is not recommended as it can damage the materials, adhesives, and cushioning system. Hand wash gently with a damp cloth and mild soap if necessary, and air dry.

'Crusher' likely refers to the impact-absorbing capabilities, 'Sonic' may indicate speed or responsiveness, and 'Knit' describes the breathable, adaptive mesh upper material.

The technical mesh is designed for maximum breathability, allowing air to circulate and keeping your feet cool and dry during exercise. It also adapts to the shape of your foot for a comfortable, personalized fit.

The reflective details are designed to be visible when hit by light sources, such as car headlights. They significantly improve visibility in low-light conditions like dawn, dusk, or night running.

Ensure you have selected the correct size. Try wearing them with athletic socks. Break them in with shorter walks before longer runs.

While durable, cushioning can degrade with extensive use. Consider replacement after significant mileage (typically 300-500 miles) as per general running shoe guidelines.

The grip is optimized for dry and moderately wet surfaces. For extremely wet conditions, exercise caution as with any athletic shoe.
