Nike Air Max 90 Trainers - Black - Yellow - UK 9.5

The Nike Air Max 90 is primarily a lifestyle trainer designed for comfort and style during casual wear. While they can accommodate light activity, they are not optimized for high-impact running or athletic performance.

Use a soft brush and a mild soap with water to clean the upper. Wipe the sole with a damp cloth. Allow them to air dry away from heat. Avoid machine washing.

The Air Max unit is Nike's proprietary cushioning technology, featuring pressurized air encapsulated in a durable pouch within the midsole, providing impact protection and comfort.

The trainers should fit snugly but comfortably. There should be a thumb's width of space between your longest toe and the end of the shoe. Ensure your heel does not slip excessively when walking.

These trainers typically feature a combination of leather, synthetic leather, and mesh for the upper, with a rubber outsole and a foam midsole containing the visible Air unit.

While the materials offer some protection, they are not waterproof. Prolonged exposure to heavy rain may soak through. It's best to avoid wearing them in very wet conditions and to dry them thoroughly if they get damp.

This can sometimes occur due to moisture trapped between layers. Try wearing them in dry conditions for a while or place a small amount of talcum powder under the insole.

Ensure the laces are adjusted correctly for a snug but not overly tight fit. Wear with appropriate socks. If the issue persists, consider trying a different size or width if available.

Over time, the foam can naturally oxidize, leading to yellowing. This is largely cosmetic. Gentle cleaning with specialized shoe cleaners might help, but it's often a natural aging process.
