Setup, Compatibility & Care
To ensure your New Balance 603 trainers maintain their shape and comfort, it is recommended to rotate your footwear rather than wearing the same pair every single day to allow the materials to recover. For sizing, these shoes follow standard UK adult sizing metrics; ensure you verify your specific size as the 603 series features a structured fit. To clean, wipe away surface dirt with a soft, damp cloth. Avoid submerging the trainers in water or using harsh industrial detergents, as these can degrade the adhesive and upper fabric integrity. Air dry at room temperature away from direct heat sources like radiators to prevent material warping.
