Setup, Compatibility & Care
To ensure the longevity of your New Balance 603 trainers, it is essential to follow basic maintenance protocols. Always ensure you are wearing the correct size, as the UK 11 fit is engineered for specific foot dimensions; wearing an incorrect size can compromise both comfort and shoe longevity. Keep the shoes clean by using a soft brush to remove loose dirt from the surface. For deeper cleaning, use a mild soap and water solution with a damp cloth, avoiding abrasive cleaning agents that could damage the outer materials. Always allow your shoes to air dry naturally away from direct heat sources, such as radiators, which can warp the materials or cause adhesives to degrade over time.
