FAQs

Are these shoes suitable for playing basketball?

While the design is inspired by 1980s basketball shoes, they are intended for lifestyle and casual use and do not offer the support or stability needed for modern competitive basketball.

How do I clean the white upper?

Wipe them down with a damp cloth. For tougher stains, use a mild leather cleaner specifically designed for synthetic materials.

Do these fit true to size?

Yes, they generally follow standard sizing. If you have wider feet, you may consider a half-size up for extra room.

Can I put these in the washing machine?

It is not recommended, as washing machines can damage the glue, materials, and overall shape of the trainers.

Are these waterproof?

The synthetic upper is water-resistant to a degree but they are not fully waterproof. Avoid wearing them in heavy rain to protect the materials.

Troubleshooting

Visible scuff marks on the white synthetic leather

Use a soft, damp cloth with a mild soap solution and gently rub the affected area. Avoid abrasive scrubbers.

Creasing at the toe box

This is natural for synthetic leather trainers. Use shoe trees when not wearing the shoes to help retain the original shape.

Insole feels less supportive over time

The included insoles are designed for comfort, but if they wear down, they can be removed and replaced with third-party orthopedic inserts.

Pros and Cons

  • Reliable durability for daily wear

Setup, Compatibility & Care

These trainers require no "break-in" period; they are designed to fit comfortably right out of the box. To maintain the crisp look of the White/Blue colorway, wipe the synthetic leather upper with a soft, damp cloth to remove surface dirt. Avoid submerging the shoes in water or using harsh detergents, as this can degrade the bonding agents and the synthetic finish. Store in a cool, dry place away from direct sunlight to prevent the white material from yellowing over time.
