Nike Cosmic Runner 4 - Black - Size 1

Yes, the Nike Cosmic Runner 4 features a springy foam midsole and tough rubber tread, making them suitable for running and other active play for children.

It is recommended to measure your child's foot and compare it to Nike's official size chart for UK children's shoe sizes. For this specific model, the size is UK 1.

No, machine washing is not recommended. It can damage the materials and construction of the shoe. Please follow the care instructions provided, which involve hand cleaning with a damp cloth and mild soap.

The elastic laces are designed for flexibility and ease of entry, but their tension is generally fixed. The primary adjustment for a snug fit comes from the hook-and-loop closure.

For optimal comfort and to prevent rubbing, we recommend wearing athletic socks that are breathable and provide adequate cushioning. Ensure socks are not too thick to affect the fit of the shoe.

This specific variant of the Nike Cosmic Runner 4 is in a Black colourway. Other colour options may be available for the Cosmic Runner series, but not for this exact product.

First, ensure you have the correct size. For fit issues, adjust the hook-and-loop strap. Make sure it's snug enough to prevent the foot from sliding but not so tight that it causes discomfort or restricts circulation. Have your child try them on with their typical socks.

The coated mesh upper is designed for durability and ease of cleaning. Use a damp cloth to wipe down the shoes after each wear. For tougher dirt, a soft brush with mild soap and water can effectively clean the surface without damaging the material. Regular cleaning extends the life and appearance of the trainers.

Check the tough rubber tread for any dirt, mud, or small debris that might be lodged in the grooves. Clean the tread thoroughly to restore its original traction. Ensure the shoes are dry before wear, as moisture can affect grip on some surfaces.
