FAQs

Are these shoes true to size?

Yes, the ASICS Japan S generally fits true to standard UK sizing for adults.

Can these be used for basketball?

While inspired by 1981 basketball shoes, they are now classified as lifestyle trainers and lack the modern support required for competitive sports.

How do I clean the white leather?

Use a soft, damp cloth with mild soap. Avoid harsh chemicals or submersing the shoes in water.

Is the insole removable?

Yes, the ORTHOLITE insole can be removed if you prefer to use custom orthotics.

Are they waterproof?

No, they are made of leather and are not waterproof. They may absorb water if worn in heavy rain.

Troubleshooting

Creasing in the leather toe box

Use shoe trees when not in use to maintain the shape of the leather.

Scuff marks on the white leather

Use a specialized leather cleaner or a gentle, non-abrasive eraser to buff away surface marks.

Insole losing support over time

Since the ORTHOLITE insole is removable, replace it with a fresh pair of third-party comfort inserts.

Setup, Compatibility & Care

Because these trainers feature leather uppers, proper maintenance is essential for preserving the white finish. To keep your pair in optimal condition, wipe the surface with a damp cloth after exposure to dirt. Avoid machine washing, which can compromise the glue and material integrity. For storage, keep the shoes in a cool, dry place away from direct sunlight to prevent leather discoloration. These trainers are standard UK sizing and are compatible with most everyday casual wardrobes, including denim, chinos, or athletic wear.
