Nike Air Max 90 Trainers - White - Size 11.5

The uppers are a combination of textile, leather, and synthetic overlays, offering a blend of breathability, durability, and style.

Use a soft cloth or brush with mild soap and cool water. Gently wipe the leather surfaces. Always air dry afterward.

While they offer good cushioning, the Nike Air Max 90 Trainers are best suited for casual wear, walking, and light athletic activities. For marathon running, specialized running shoes with advanced support and cushioning are recommended.

The visible Max Air unit in the heel provides exceptional cushioning, absorbs impact, and helps maintain the shoe's shape and performance over time.

Utilize the lace-up fastening system and ensure the laces are tied snugly. The padded ankle collar also contributes to a secure and comfortable feel.

The trainers typically have a removable insole, which may allow space for custom orthotics. It's advisable to check the fit with your specific orthotics before purchase or extended wear.

Nike generally offers a limited warranty against manufacturing defects. Specific warranty details can be found on the official Nike website or by contacting their customer service.

Ensure laces are tied securely using a double knot if necessary. Adjust the lacing pattern for a tighter fit through the midfoot.

The visible Air unit is designed for cushioning and shape retention. If you suspect damage, discontinue use and consult Nike's warranty information or a retailer.

Allow a break-in period of a few wears. Ensure the correct size and width are selected. Check for any internal stitching or material defects. Adjust lacing to relieve pressure points.

This can sometimes occur due to friction between the sole and insole, or moisture. Try removing the insole, drying both thoroughly, and reinserting it. A small amount of talcum powder under the insole might also help.
