To protect new children's shoes from dirt and moisture, here are a few tips you can follow:

1. Waterproof spray : use a waterproof spray suitable for the material of the shoes. Spray the shoes evenly with the spray and allow them to dry completely according to the manufacturer's instructions. This helps repel moisture and prevents water from seeping into the shoes.

2. Shoe protectors: Consider using shoe protectors, such as shoe covers or rubber overshoes, in inclement weather or during activities where the shoes need extra protection. These can be worn over the shoes to protect them from mud, rain and other dirt.

3. Regular cleaning : Clean the shoes regularly to remove dirt and stains. Use a soft brush or damp cloth to gently wipe away the dirt. Avoid aggressive cleaning agents that can damage the material and follow the manufacturer's cleaning instructions if necessary.

4. Store dry : Make sure the shoes are completely dry before storing them. If the shoes get wet, allow them to dry naturally, away from direct heat sources such as radiators. Store them in a cool and dry place to prevent mold and odor formation.

5. Regular inspection : check the shoes regularly for any damage or worn spots. Repair minor defects as quickly as possible to prevent further damage.

By following these tips , you can protect your new children's shoes against dirt and moisture, making them look good and last longer.
