Nike Air Max 90 Trainers - White/Red - UK 8.5

While they offer good cushioning for walking and everyday wear, the Air Max 90 are primarily designed as lifestyle trainers. For high-impact running, dedicated running shoes are recommended.

The shoes should feel snug but not tight, with enough room in the toe box for your toes to wiggle slightly. Ensure there's no excessive pressure on any part of your foot.

The materials offer some protection, but they are not waterproof. They can handle light moisture, but prolonged exposure to heavy rain is not recommended as it may affect the materials and comfort.

Nike typically offers a limited warranty against manufacturing defects. Specific warranty details can usually be found on the Nike website or the original purchase receipt.

Regular cleaning after wear, using appropriate cleaning products, and storing them away from direct sunlight will help maintain the white color. Consider applying a shoe protector spray.

The Air Max 90 generally has a standard fit. If you have particularly wide feet, it's advisable to try them on first or look for reviews that specifically address fit for wider feet.

This can sometimes occur due to air moving within the sole unit or friction between layers. Try walking on different surfaces, or ensure the insoles are properly seated. If persistent, it may be a characteristic of the shoe.

Try double-knotting the laces. You can also replace the laces with a more textured or thicker pair that are less prone to slipping.

Ensure you are wearing appropriate socks. The shoes may need a short break-in period. If the rubbing persists, check if the size is correct or consider thicker socks.

Wipe down the shoes regularly with a damp cloth after each use. For more significant marks, use a specialized shoe cleaner or a mild soap and water solution. Protectant sprays can also help repel dirt.
