Yes, the high level of cushioning makes it an excellent choice for marathon training and race day, offering comfort over long distances.

The Flyknit upper is designed to be breathable, lightweight, and provide a flexible, sock-like fit that adapts to your foot's shape, enhancing comfort and support.

These shoes are primarily designed for road running. The rubber outsole provides good traction on pavement and other hard surfaces, but it may not offer sufficient grip or protection for technical trail running.

Clean the shoes by hand using a soft brush and a mild detergent mixed with cool water. Wipe with a damp cloth and allow them to air dry completely away from direct heat.

The ZoomX Invincible Run is characterized by its maximalist cushioning approach, using Nike's softest and most responsive ZoomX foam, prioritizing comfort and impact protection above all else.

Adjust the lacing system. Ensure the laces are threaded evenly and tied snugly but not so tight that they restrict circulation. For a tighter feel, try different lacing techniques like a runner's loop.

Ensure the outsole is clean and free from mud or debris. For persistent slippage, consider the surface conditions; the rubber outsole is designed for optimal grip on most road surfaces, but extreme conditions may affect performance.

Ensure the shoes were not over-tightened during lacing. If the Flyknit has lost its structure, it may be a sign of excessive wear or improper care. Consider using them for less intense activities or for shorter runs.
