Nike Air Max 90 - Black - Size: 11

While the Nike Air Max 90 features advanced cushioning, it is primarily designed as a lifestyle and casual wear shoe. It provides excellent comfort for everyday walking and standing but is not optimized for high-performance running or intense athletic sports. For those activities, dedicated running or training shoes would be more appropriate.

For the leather and synthetic parts, use a soft, damp cloth with a small amount of mild soap. For textile areas, a soft brush can help. Clean the midsole and outsole with a brush and mild soap. Always air dry your shoes away from direct heat or sunlight. Avoid machine washing or submerging them in water.

The Visible Max Air Unit is a groundbreaking Nike cushioning technology located in the heel. It consists of a durable, flexible bag filled with pressurized air. Its purpose is to provide superior impact absorption, energy return, and long-lasting cushioning, contributing significantly to the shoe's comfort.

Generally, Nike Air Max 90s are known to fit true to size for most individuals. However, fit can vary slightly based on individual foot shape and preference. If you are between sizes, it's often recommended to try the larger size or consult a size guide specific to Nike footwear.

The Nike Air Max 90 features a multi-material upper with leather and synthetic overlays, which offers some resistance to light moisture. However, they are not waterproof. For heavy rain or very wet conditions, it's advisable to wear waterproof footwear to keep your feet dry and protect the shoes.

The 30th Anniversary edition of the Nike Air Max 90 features subtle design tweaks that bring it closer to Tinker Hatfield's original 1990 design. These include adjustments to the mudguard, toe box height, and heel branding shape, along with extra ankle padding, aiming to provide a more authentic retro feel and enhanced comfort.

This can sometimes be caused by friction between the insole and the shoe's interior. Try removing the insole, cleaning underneath it, and then sprinkling a small amount of baby powder or cornstarch inside the shoe before reinserting the insole. If the squeak persists, it might be due to the outsole; ensure it's clean and free of debris.

For light scuffs on the foam midsole, a melamine foam eraser (like a 'magic eraser') can often work wonders. For general dirt, use a soft brush or sponge with a mild soap and water solution, gently scrubbing the affected areas. Regular cleaning will prevent dirt from setting in.

While the shoes feature textile elements, the leather and synthetic overlays can limit overall breathability. Ensure you are wearing appropriate socks (e.g., moisture-wicking materials). Allowing shoes to air out completely between wears can also help. For very hot climates, these may not be the most breathable option.

Over time and with extensive use, the cushioning properties of any shoe can naturally diminish. Ensure the visible Max Air unit is not punctured or damaged. Keep the outsole clean, as trapped debris can sometimes affect the feel. For older shoes, a decrease in responsiveness is a normal sign of wear.
