FAQs

Are these shoes suitable for running?

No, the Japan S is designed as a lifestyle and casual sneaker, not for running or intensive athletic activity.

How should I clean the white leather?

Use a damp, soft cloth. Avoid machine washing, as the water and agitation can damage the leather and the structure of the shoe.

Are these shoes true to size?

Yes, they generally follow standard adult sizing conventions. If you are between sizes, it is usually safer to size up.

Can I remove the insoles?

Yes, the ORTHOLITE insoles are removable and can be replaced if needed.

What is the material of the upper?

The upper is constructed from high-quality leather.

Is this a unisex model?

Yes, the Japan S is designed as a unisex trainer suitable for all adults.

Troubleshooting

Creasing in the leather toe box

This is natural for leather footwear. Use shoe trees when not in use to help maintain shape and minimize deep creases.

Surface scuffs on the white leather

Gently use a magic eraser or a damp cloth with mild soap to buff out minor surface marks.

Insole feels less comfortable over time

The ORTHOLITE insole is removable; you can replace it with a fresh pair of liners to restore underfoot comfort.

  • Durable cupsole construction for daily use

Setup, Compatibility & Care

To ensure your ASICS Japan S trainers remain in good condition, consider the following:

  • Breaking In: New leather shoes may feel slightly stiff; wear them for short durations indoors initially to allow the material to soften.
  • Cleaning: Wipe the leather upper with a damp, soft cloth. Avoid using harsh chemicals that may strip the finish. Use dedicated leather cleaners for stubborn stains.
  • Storage: Store in a cool, dry place away from direct sunlight to prevent leather drying and discoloration.
  • Compatibility: These trainers fit true to standard adult sizing. If you have particularly wide feet, consider using thinner socks for a better fit.
