Nike Air Max 90 Premium Trainers - Grey - Size 13

While the Air Max 90 features cushioning inspired by running technology, they are primarily designed for casual wear and lifestyle. For marathon running, specialized performance running shoes offering specific support and cushioning would be recommended.

Ensure there is about a thumb's width of space between your longest toe and the front of the shoe when standing. The heel should feel snug without slipping.

The trainers offer some protection, but they are not waterproof. Prolonged exposure to heavy rain may lead to wetness inside. It's best to avoid wearing them in very wet conditions and ensure they dry completely afterward.

The 'Premium' designation typically indicates the use of higher-quality materials and potentially enhanced construction details compared to standard models.

Clean your trainers as needed, especially after exposure to dirt or heavy use. Regular spot cleaning will help maintain their appearance.

The Air cushioning is designed to be durable for the typical lifespan of the shoe under normal wear conditions. It does not deflate like a balloon but can lose some of its responsiveness over extensive use.

Yes, the Air Max 90 series is available in a wide range of colours and designs. Please check other listings for available variants.

Ensure laces are tied securely using a double knot. Consider replacing worn laces with new ones.

Verify the fit is correct and not too tight. Ensure the lacing system is adjusted properly to support the foot. Break-in period may be required.

Gently wipe with a damp cloth. For stubborn marks, use a mild shoe cleaner specifically designed for trainers and follow its instructions carefully.
