Crusher Sonic Knit sneakers - EA7 - Black - Trainers - UK 6.5

The dual-density cushioning means the midsole is constructed with two different materials or densities. One provides a softer landing and impact absorption, while the other offers a firmer, more responsive feel for energy return during the push-off phase of your stride.

Lace the shoes snugly but not overly tight. The mesh is designed to adapt to your foot's shape during movement, so a secure, comfortable fit is key to leveraging its adaptive qualities.

These sneakers are primarily designed for road running and gym use due to their lightweight construction and smooth outsole tread. Trail running may require shoes with more aggressive tread patterns and enhanced protection.

Clean your sneakers as needed, especially after runs where they may have accumulated dirt or sweat. Regular gentle cleaning helps maintain the material's integrity and performance.

The Polyurethane (PU) inserts provide structural support and stability to the shoe, particularly in key areas. They help control foot pronation and supination, contributing to a more stable and efficient running form.

While engineered for running, their comfort and support features may make them suitable for general fitness activities. However, they may not offer the specific support or durability required for intense cross-training or sports with lateral movements.

Ensure the laces are tied evenly and the shoe is properly seated on the foot. Break-in period might be required for optimal cushioning experience.

Clean the mesh upper gently with a damp cloth and allow to air dry. Ensure no debris is lodged in the mesh.

Check the outsole for excessive wear or debris. Ensure the lacing system provides a secure fit. The PU inserts are designed for stability, but proper lacing is key.

This is a design feature for support and cushioning. If discomfort persists after a break-in period, consider if this midsole height is suitable for your gait and biomechanics.
