Product Information
Full details
The adidas Core Bubble Jr trainers are designed specifically for active children who need a reliable, comfortable shoe for everyday wear. These trainers excel at providing a lightweight, cushioned experience through a soft one-piece EVA sole, making them an ideal choice for school, play, and casual outings. While they offer exceptional convenience with their laceless, slip-on design, parents should note that the mesh material is best suited for dry weather conditions rather than heavy rainfall or muddy environments.

FAQs
Are these shoes machine washable?
No, it is recommended to clean them by hand using a damp cloth and mild soap to protect the foam sole and mesh fabric.
Are these trainers waterproof?
No, the breathable mesh upper is designed for ventilation and will allow water to pass through if walking in rain or puddles.
Do these shoes require socks?
It is highly recommended to wear these with socks to maximize comfort and hygiene.
Can the insoles be removed?
The Core Bubble Jr typically features a fixed inner construction to support the laceless, slip-on functionality.
How do I ensure the right fit?
Measure the child's foot in centimeters and compare it against the adidas junior size guide, ensuring there is roughly a thumb's width of space at the toe.
Troubleshooting
Shoes feel loose during movement
Ensure the feet are positioned correctly inside the shoe and that the heel tab has been pulled up properly to secure the collar against the ankle.
Outer mesh appears dusty or dirty
Gently brush the mesh with a soft-bristled brush when dry to remove loose dirt before wiping with a damp cloth.

Setup, Compatibility & Care
These trainers come ready to wear right out of the box with no complex setup required. For care, it is recommended to spot clean the mesh upper with a mild detergent and a soft cloth to maintain the vibrant color and fabric integrity. The EVA sole can be wiped down with a damp cloth to remove playground dirt or grass stains. Avoid machine washing or drying, as high heat can deform the EVA structure. Ensure the shoes are fully air-dried away from direct heat sources before their next use to maintain long-term comfort.
