5. Care and Maintenance
To maintain the appearance and extend the life of your New Balance CT300 V3 sneakers, follow these care instructions:
- Cleaning: For suede and mesh materials, gently brush off loose dirt with a soft brush. For tougher stains, use a specialized sneaker cleaner designed for these materials. Avoid harsh chemicals or machine washing.
- Drying: Allow shoes to air dry naturally at room temperature. Do not use direct heat sources like radiators or hair dryers, as this can damage materials.
- Storage: Store sneakers in a cool, dry place away from direct sunlight. Stuffing them with paper can help maintain their shape.
- Discoloration Warning: Please note that sweat may cause discoloration of the materials over time. Regular cleaning and proper drying can help mitigate this.
