FAQs
Are these shoes true to size?
Yes, they generally fit true to standard adult sizing, though the layered construction offers a more structured fit.
Can I use these for marathon running?
No, these are heritage lifestyle trainers designed for casual use rather than long-distance athletic running.
Are they waterproof?
No, they feature mesh underlays for breathability and are not water-resistant.
How do I clean the mesh material?
Use a soft brush to remove loose dirt and a damp cloth for spots; avoid harsh chemicals.
Is this a unisex model?
Yes, the New Balance 603 is designed as a unisex trainer suitable for all genders.
What is the function of the flex grooves?
The flex grooves are located in the outsole to allow the shoe to bend naturally with your foot's movement.
Troubleshooting
Laces coming undone
Ensure the laces are threaded properly through both the metal eyelets and fabric loops to maintain consistent tension.
Surface scuffing on silver overlays
Use a specialized sneaker cleaning wipe or a very soft cloth with minimal water to gently buff the area.
Midsole feels stiff initially
The foam requires a short break-in period; wear the shoes for a few hours at a time to allow the materials to soften and conform to your foot.

Setup, Compatibility & Care
To ensure your New Balance 603 trainers last, avoid submerging them in water. For general cleaning, use a soft-bristled brush to remove dry dirt from the mesh and metallic overlays. If stains persist, use a damp cloth with mild soap, testing on a small, inconspicuous area first. The laces can be removed and hand-washed separately. Regarding compatibility, these fit true to size for most, though the layered paneling provides a structured, supportive fit that may feel slightly snugger initially compared to flexible knit shoes. Store in a cool, dry place away from direct sunlight to prevent the metallic overlays from fading.
