Setup, Compatibility & Care
To ensure the longevity of your New Balance 603 trainers, follow these basic care instructions:
- Cleaning: Gently wipe away surface dirt with a soft, dry brush. For more stubborn stains, use a cloth dampened with mild soap and cold water; avoid submerging the shoes in water.
- Drying: Always air-dry at room temperature. Never place shoes near radiators, heaters, or direct sunlight, as excessive heat can warp the materials and adhesives.
- Storage: Store in a cool, dry place away from direct light to maintain the integrity of the fabric and color.
- Compatibility: These trainers fit true to size according to standard UK adult measurements. For those wearing custom orthotics, the internal space is generally accommodating, though it is recommended to test the fit with your specific inserts.
