FAQs

Are these sneakers suitable for running?

No, the ASICS Japan S is designed as a casual, lifestyle trainer and does not provide the technical support or cushioning required for running.

How do I choose the right size?

The ASICS Japan S is available in standard UK adult sizing. Refer to your previous ASICS size or measure your foot to match the provided size chart.

Are they water-resistant?

While leather provides some protection against light splashes, these shoes are not waterproof and should be kept away from heavy rain to protect the leather material.

Can I put these shoes in the washing machine?

No, machine washing can damage the leather and the structure of the cupsole. Hand-cleaning is recommended.

What is the ORTHOLITE insole benefit?

ORTHOLITE insoles provide long-term cushioning, high-level breathability, and moisture management to keep feet cool and comfortable.

Troubleshooting

Creasing on the toe box area

Leather creasing is a natural characteristic of leather footwear; use shoe trees when not in use to help maintain the shape.

Difficulty keeping the white leather clean

Use a specialized leather cleaner or a gentle wipe after each use to prevent dirt from setting into the grain.

Insole comfort fading over time

If the ORTHOLITE insole loses support, it can be replaced with a third-party aftermarket insert of the same thickness.

Pros and Cons

  • ORTHOLITE insole offers excellent cushioning for all-day wear
  • Durable leather construction holds up well to everyday activities
  • Iconic heritage styling that stays relevant

Setup, Compatibility & Care

To ensure your ASICS Japan S trainers last, keep these care tips in mind:

  1. Cleaning: Wipe the leather surface with a soft, damp cloth. Avoid submerging the shoes in water or using harsh industrial chemicals that may yellow the leather or finish.
  2. Storage: Store in a cool, dry place away from direct sunlight to prevent potential leather discoloration.
  3. Usage: These trainers are standard unisex sizes. Ensure you use the correct UK sizing guide to find your perfect fit. If the ORTHOLITE insole becomes heavily soiled, remove it and clean it separately with mild soap and water, ensuring it is completely air-dried before re-insertion.
