Nike Air Max 90 - Black - UK 13

For general cleaning, wipe the mesh and leather with a soft, damp cloth. For deeper cleaning, use a mild soap solution with a soft brush for mesh and a specialized leather cleaner for the leather parts. Always air dry your shoes away from direct heat.

The Nike Air Max 90 is primarily designed as a lifestyle and casual sneaker, offering comfort for daily wear and walking. While it has roots in running shoe technology, it is not optimized for high-performance running or intense sports activities.

The visible Air sole unit is a transparent capsule embedded in the midsole, containing pressurized air. It provides lightweight cushioning and shock absorption, and it's a signature design element of the Air Max series, allowing you to see the technology at work.

Nike Air Max 90s are generally considered to fit true to size for most people. If you typically wear a UK 13 in Nike shoes, this size should be consistent. However, personal fit preference can vary.

The mesh and leather upper provides some protection, but the shoes are not waterproof. Prolonged exposure to heavy rain should be avoided. If they get wet, let them air dry naturally and consider applying a water-repellent spray for future protection.

Store them in a cool, dry place away from direct sunlight. Using shoe trees (cedar ones are best for absorbing moisture and odor) can help maintain their shape. Avoid cramming them into tight spaces.

This can sometimes happen due to friction between the insole and the sole, or moisture. Try removing the insole, cleaning the inside of the shoe and the bottom of the insole, then letting them air dry completely before reinserting. A sprinkle of baby powder under the insole can also help reduce friction.

For light scuffs, a soft, damp cloth can often buff them out. For deeper marks or to restore shine, use a suitable black leather conditioner or polish designed for footwear. Apply sparingly and buff according to the product instructions.

Remove the insoles and let both the shoes and insoles air out in a well-ventilated area for at least 24 hours. You can also use shoe deodorizers, cedar shoe trees, or sprinkle baking soda inside the shoes overnight (then vacuum it out) to absorb odors.

Gently scrub the mesh with a soft brush (like an old toothbrush) dipped in a solution of mild soap and water. Avoid harsh chemicals. Rinse by wiping with a clean, damp cloth and let air dry completely.

Ensure you have the correct size. While the UK 13 is a specific size, individual foot shapes vary. Try adjusting the lacing technique; for example, skip a lace hole if too tight, or use all lace holes for a more secure fit. Wearing appropriate socks can also make a difference.
