Nike Air Max 90 - Black - Size 11

While the Air Max 90 offers cushioning, it is primarily designed for casual wear and lifestyle. For dedicated running, specialized running shoes are recommended.

The shoe should feel snug but not tight. There should be a thumb's width of space between your longest toe and the end of the shoe. Ensure the heel doesn't slip excessively.

It is not recommended to machine wash the Nike Air Max 90, as this can damage the materials and the cushioning system. Hand washing is the preferred method.

Nike typically offers a limited warranty against manufacturing defects. Please refer to the official Nike website or your retailer for specific warranty details and duration.

The black colorway is generally durable, but like any dark shoe, it may show scuffs or marks more prominently than lighter colors. Regular cleaning will help maintain its appearance.

Yes, the insoles are typically removable and can be replaced with custom orthotics or different insoles for added comfort or support.

This can sometimes occur due to the air unit or friction between parts. Try walking on different surfaces or ensure laces are tied evenly. If persistent, a small amount of talcum powder under the insole might help.

Replace laces with a new pair of a similar length and material. Avoid overtightening laces, which can put unnecessary stress on them.

Ensure the correct size has been purchased and laces are adjusted properly. Break in the shoes gradually by wearing them for short periods initially.
