Setup, Compatibility & Care
To get the best performance, ensure the laces are adjusted so the shoe feels snug around the midfoot without restricting blood flow. For sizing, the New Balance 603 follows standard adult UK sizing protocols; if you prefer thicker socks, consider how they interact with the interior cushioning. To maintain the appearance of the suede elements, use a soft-bristled brush to remove dust and dirt regularly. Avoid soaking the shoes in water or putting them in a tumble dryer, as heat and excessive moisture can damage the adhesive and the texture of the suede. If they get wet, air dry them naturally at room temperature away from direct heat sources.
