FAQs

Are these shoes suitable for running?

Yes, they feature a runner-inspired profile suitable for casual play and light activity, though they are not intended for competitive athletic racing.

How do I determine the right size?

Measure the child's foot in the afternoon when it is at its largest and ensure there is roughly a thumbnail's width of space at the toe.

Can these be machine washed?

It is generally recommended to hand-clean them with a damp cloth to protect the structural integrity of the materials and adhesives.

Are these water-resistant?

These trainers are designed for breathability and are not waterproof.

What gender are these shoes for?

The Assert 11 series is versatile and inclusive, with many colorways suitable for all children.

Troubleshooting

Trainer feels tight after extended wear

Ensure the laces are adjusted correctly to allow for natural foot expansion; verify that the socks worn are not excessively thick.

Outsole collecting debris

Use a dull plastic tool or a stiff brush to gently remove gravel or mud from the tread patterns to maintain optimal traction.

Setup, Compatibility & Care

To ensure the longevity of your Assert 11 Trainers, follow these care guidelines:

  1. Cleaning: Wipe the exterior surface with a soft, damp cloth. For tougher dirt, use a mild soap solution and a soft-bristled brush to gently scrub the fabric and outsole.
  2. Drying: Always allow the trainers to air dry at room temperature. Avoid placing them directly on radiators or heaters, as excessive heat can warp the cushioning materials and adhesives.
  3. Storage: Store in a cool, dry place away from direct sunlight to prevent material degradation and color fading.
  4. Compatibility: These are standard UK sizing for children. Ensure the fit leaves about a thumbnail's width of space at the toes to accommodate growth and natural foot swelling during activity.
