ON Running Cloud Sky Trainers - Grey - Kids - UK 4.5

No, the ON Running Cloud Sky trainers are made with breathable mesh and are not waterproof. They are designed for ventilation and comfort in dry conditions.

CloudTec is ON Running's proprietary cushioning technology. It uses unique 'clouds' on the outsole that compress upon impact to absorb shock and then 'explode' for a responsive rebound.

The Speedboard is a thin, responsive plate embedded within the midsole. It is engineered to work with CloudTec to enhance energy return and provide a more propulsive feel during the stride.

Refer to the ON Running size chart and measure your child's foot. Ensure there is a small amount of space (about a finger's width) between the longest toe and the end of the shoe for comfort and growth.

While they offer responsive cushioning, they are primarily designed for everyday wear and light activity. For serious running competitions, specialized running shoes with more advanced performance features might be more appropriate.

The trainers feature a textile and synthetic upper with a synthetic sole. The upper prioritizes breathability and lightweight comfort.

The lifespan depends on usage frequency and intensity. For active children, they are generally expected to last through a season of regular wear before significant signs of wear and tear appear on the cushioning and outsole.

Adjust the lacing to find a more secure or comfortable fit. If the size is fundamentally incorrect, consider exchanging for a different size.

Over time, cushioning can compress. Ensure the shoes are the correct size and consider if they have reached the end of their useful life for optimal performance.

Check the outsole for excessive wear. Clean the outsole to remove any mud or debris that may be affecting traction. These shoes are designed for general traction, not extreme conditions.
