3. Setup and First Use
Before wearing your new NIKE Air Max 90 sneakers, follow these simple steps for optimal comfort and fit:
- Unboxing: Carefully remove the sneakers from their packaging.
- Lacing: Ensure the laces are threaded correctly through all eyelets. Adjust the lacing tension to provide a snug yet comfortable fit across your foot. Avoid overtightening, which can restrict circulation.
- Initial Try-On: Wear the sneakers with the type of socks you typically use. Walk around for a few minutes to assess the fit. Your toes should have a small amount of space at the front, and your heel should feel secure without slipping.

4. Operating (Wearing) Instructions
The NIKE Air Max 90 is designed for versatile use, from daily wear to light athletic activities. To maximize comfort and performance:
- Proper Fit: Always ensure your shoes are properly laced and tied before any activity to prevent injury and ensure stability.
- Intended Use: These sneakers are ideal for casual wear, walking, and road running. While durable, they are not designed for heavy-duty sports like basketball or trail running, which require specialized footwear.

5. Maintenance and Care
Proper care will extend the life and appearance of your NIKE Air Max 90 sneakers:
- Cleaning the Upper: Use a soft brush or cloth with mild soap and water to gently clean the mesh and synthetic leather surfaces. Avoid harsh chemicals or abrasive cleaners.
- Cleaning the Sole: A stiff brush can be used to remove dirt and debris from the rubber sole.
- Drying: Air dry your sneakers at room temperature. Do not use direct heat sources like radiators or tumble dryers, as this can damage materials.
- Storage: Store sneakers in a cool, dry place away from direct sunlight. Stuffing them with paper can help maintain their shape.
- Avoid Machine Washing: Machine washing is not recommended as it can damage the shoe's structure and materials.

6. Troubleshooting
If you encounter any issues with your NIKE Air Max 90 sneakers, consider the following common solutions:
- Discomfort/Rubbing: Ensure you are wearing appropriate socks. Re-adjust lacing to relieve pressure points. If discomfort persists, verify you have the correct size (refer to the size guide).
- Squeaking: Sometimes new shoes may squeak. This often resolves with wear. If it persists, try applying a small amount of baby powder under the insole.
- Odor: Allow shoes to air out after each use. Consider using shoe deodorizers or baking soda sachets to absorb moisture and odors.
