adidas Cloudfoam Flex Trainers - Black - UK 12

No, the adidas Cloudfoam Flex Trainers are designed for casual wear and light activities. They are not engineered with the specialized support and cushioning required for marathon running.

If you typically find standard-width shoes uncomfortable, press on the sides of your feet, or need more room in the toe box, the wide fit is likely suitable for you. The synthetic leather upper offers some flexibility.

It is not recommended to machine wash these trainers. Machine washing can damage the adhesives, materials, and cushioning of the shoe. Hand washing with a damp cloth and mild soap is the preferred method.

The adidas Cloudfoam Flex Trainers weigh approximately 631 grams for the pair in UK size 12.

The upper is constructed from synthetic leather, providing durability and a sleek appearance.

Store the trainers in a cool, dry place away from direct sunlight. Using shoe trees can help maintain their shape.

Loosen the laces and ensure they are not tied too tightly. If the issue persists, consider if the 'wide fit' is sufficient for your needs or if insoles are contributing to tightness.

The Cloudfoam cushioning may compress with extensive use. Ensure the shoes are not being used for activities beyond their intended casual or light training purpose. Regular cleaning can also help maintain material integrity.

This can sometimes occur due to friction between different shoe components. Try applying a small amount of talcum powder or cornstarch inside the shoe, particularly around the sockliner, and see if this resolves the noise.
