FAQs

Are these shoes machine washable?

It is recommended to clean them by hand using a damp cloth and mild soap to maintain the integrity of the materials.

Are these suitable for long-distance running?

These are designed as versatile trainers for daily activities and play, rather than specialized long-distance running shoes.

How do I choose the right size?

Measure the foot with a ruler and consult a standard Nike kids' size chart, leaving a small amount of room for growth.

Can I replace the insoles?

Yes, if the provided insoles wear out, they can be removed and replaced with standard athletic orthotics or replacement insoles.

What surfaces are these best for?

They perform best on standard surfaces like pavement, school tracks, and indoor gymnasium floors.

Troubleshooting

Shoes feel too tight after a few weeks

Kids' feet grow rapidly; check if it is time to size up to ensure adequate circulation and comfort.

Visible dirt accumulation on the upper

Use a soft-bristled brush to gently remove dried mud before wiping with a damp cloth.

Laces coming untied frequently

Double-knot the laces or consider replacing them with elastic no-tie laces for a more secure, consistent fit.

Setup, Compatibility & Care

To ensure the longevity of your Nike Cosmic Runners, check that the laces or closure systems are tightened properly before each use to prevent tripping hazards. For maintenance, keep the shoes away from heavy mud or water, as excess moisture can degrade the internal adhesives over time. Clean the exterior by wiping with a soft, damp cloth and mild soap; avoid machine washing or drying, which can warp the materials and ruin the support structure. If the insoles become damp, remove them and air-dry them naturally at room temperature.
