FAQs

Are these shoes suitable for running?

No, these are specialized court trainers. They lack the heel-to-toe drop and gait-pattern support required for efficient running.

Can I use these for indoor sports?

Yes, the non-marking outsole and grip pattern make them highly effective for indoor court surfaces like gymnasium wood or synthetic mats.

How do I determine my size?

These trainers follow standard UK sizing for adults. If you are between sizes, we recommend opting for the larger size to allow for thick court socks.

Are the insoles removable?

Yes, the insoles are removable, allowing you to insert your own custom orthotics if required.

How long should I expect them to last?

Longevity depends on intensity and frequency, but regular competitive players typically replace court shoes every 6 to 9 months.

Do these shoes need a break-in period?

While they feel comfortable out of the box, the upper materials and midsole foam usually feel most responsive after 2-3 hours of active use.

Troubleshooting

Feeling of slipping inside the shoe

Adjust the laces using the secondary eyelet for a 'runner's loop' to secure the heel more effectively.

Accumulated court dust reducing grip

Wipe the outsole with a damp towel periodically during play to restore the rubber's traction capabilities.

Odour buildup after intense sessions

Remove the insoles after play and store the shoes in a well-ventilated area to allow moisture to evaporate.

Pros and Cons

Pros

  • Excellent lateral support for rapid side-to-side movement
  • Lightweight feel due to FlyteFoam integration
  • Durable construction specifically for high-intensity court use
  • Consistent grip on indoor and hard outdoor courts

Cons

  • Not suitable for long-distance road running
  • Court-specific outsole may wear down quickly on asphalt
  • Firm cushioning may require a brief break-in period for some users

Setup, Compatibility & Care

To ensure optimal performance, ensure your Asics Sonicsmash FF Trainers are laced snugly across the midfoot to prevent internal slippage. These shoes are compatible with standard court surfaces; using them on grass or extremely abrasive, rough outdoor concrete may accelerate outsole wear. For care, avoid machine washing. Wipe down the upper with a soft, damp cloth and mild soap to remove dust. Allow the shoes to air dry naturally away from direct heat sources like radiators, which can compromise the foam integrity and glue bonds.
