Nike Air Max 90 Trainers - Black - Size 11

While the Nike Air Max 90 offers comfort and cushioning, they are primarily designed for casual wear and heritage style. For marathon running, specialized running shoes with advanced support and cushioning systems would be more appropriate.

It is recommended to measure your foot and compare it to Nike's sizing chart. Trying them on in person, if possible, is the best way to ensure a comfortable fit, as personal preference for tightness can vary.

No, it is not recommended to put Nike Air Max 90 trainers in a washing machine. Machine washing can damage the materials, adhesives, and the cushioning unit. Hand washing with mild soap and water is the preferred method for cleaning.

Visible Air cushioning refers to Nike's technology where the air-filled cushioning unit in the sole is exposed and visible through cutouts in the midsole. This provides both shock absorption and a distinctive aesthetic feature.

Clean your trainers as needed, especially after exposure to dirt or significant wear. Regular spot cleaning and periodic deeper cleaning will help maintain their appearance and longevity.

The overlays are typically made of leather and synthetic materials, designed to provide structure, support, and durability to the textile upper.

Ensure laces are loosened before putting on. If still tight, consider wearing thinner socks or breaking them in over shorter periods.

The cushioning may have compressed over time. Ensure the Air unit is intact and not deflated. Consider replacement if the shoes are heavily worn.

Clean the Waffle outsole to remove any debris. Be cautious when walking on wet surfaces, as the rubber outsole's grip may be compromised.

Wipe gently with a damp cloth. For stubborn stains on leather, use a dedicated leather cleaner sparingly.
