FAQs

Are these shoes suitable for running?

No, the Japan S is a lifestyle sneaker designed for casual walking and fashion rather than athletic performance.

Does the synthetic leather stretch over time?

Synthetic materials typically maintain their shape better than natural leather and will stretch very little.

How do I ensure the best fit?

ASICS generally fit true to size. It is recommended to measure your feet in the afternoon when they are slightly swollen for the most accurate fit.

Are these shoes machine washable?

It is not recommended to machine wash these sneakers, as it can damage the glue and construction of the cupsole.

Are they made from animal products?

No, the model utilizes synthetic leather, making it suitable for those seeking to avoid natural leather products.

Troubleshooting

Visible scuffs on white synthetic leather

Use a soft-bristled brush or a cloth dipped in mild soapy water to gently spot-clean the affected area.

Insole feels less supportive after long-term wear

Remove the original insole and replace it with an aftermarket support insert if necessary.

Setup, Compatibility & Care

As these trainers arrive ready to wear, no mechanical setup is required. To ensure a proper fit, verify your UK size against the standard ASICS sizing chart. To maintain the trainers, wipe the synthetic leather upper with a damp cloth after use to prevent dirt build-up. Avoid submerging the shoes in water or using harsh chemical cleaners, as this can degrade the synthetic materials. For optimal lifespan, alternate your footwear to allow the internal cushioning to fully decompress.
