FAQs

Are these shoes machine washable?

It is recommended to clean them by hand with a damp cloth to preserve the shape and elasticity of the straps.

Are these trainers suitable for wide feet?

The elasticized design offers a snug fit, which may feel tight for children with wider feet; you might need to size up.

What surfaces are these shoes best for?

The flex grooves on the outsoles provide excellent traction on playgrounds, school floors, and pavement.

Do these shoes require socks?

While they can be worn with or without socks, wearing thin sports socks is recommended for added comfort and moisture management.

How do I ensure I have the right size?

Measure your child's feet in the afternoon when they are at their largest and compare them to the standard Nike children's size guide.

Troubleshooting

Difficulty pulling the shoe on

Ensure the heel tab is pulled fully outwards while inserting the foot to maximize the opening size.

Outer material showing signs of dirt

Use a damp microfiber cloth to spot clean the upper surface immediately after outdoor use to prevent staining.

Setup, Compatibility & Care

Because these are slip-on shoes, there is no technical setup required. To ensure a long lifespan for your Nike Flex Runner 4 trainers:

  1. Cleaning: Use a soft-bristled brush to remove dried mud or dirt. For deeper cleaning, wipe the fabric with a damp cloth and mild soap; avoid submerging them in water or using harsh detergents.
  2. Storage: Keep in a cool, dry place away from direct heat sources to maintain the elasticity of the straps.
  3. Compatibility: These trainers are standard UK children's sizes; if your child prefers wearing thick sports socks, you may want to consider this when checking for the best fit.
