FAQs

Are these shoes suitable for running?

No, the Japan S is a lifestyle trainer based on vintage court shoes and does not contain the technical support required for running.

What material is the upper made from?

The upper is constructed from high-quality synthetic leather.

Are these trainers true to size?

Yes, they are designed to fit standard adult sizing, but it is always recommended to refer to the official size chart.

Can I replace the insoles?

The insoles are generally removable, allowing you to insert custom orthotics if required.

How do I maintain the white finish?

Regularly wiping the shoes with a damp cloth prevents dirt buildup and keeps the material looking fresh.

Are these shoes unisex?

The series is available in both male and female specific sizing, though the aesthetic is universally styled.

Troubleshooting

Creasing at the toe box

This is normal for synthetic leather; using shoe trees when not in use can help maintain the shape.

Scuff marks on the upper

Use a soft eraser or a damp cloth with a tiny amount of mild dish detergent to gently buff the marks.

Setup, Compatibility & Care

To ensure the longevity of your ASICS Japan S trainers, keep them away from excessive moisture and extreme heat sources like radiators. For cleaning, wipe the synthetic leather uppers with a soft, damp cloth and mild soap to remove surface dirt. Avoid machine washing or submerging the shoes in water, as this can degrade the adhesives. Ensure the shoes are fully air-dried away from direct sunlight after cleaning. When choosing sizes, these trainers generally follow standard adult UK sizing; verify your fit using a brannock device or by measuring your foot length against the ASICS size guide.
