2. Setup and First Use
2.1 Unboxing and Inspection
Upon receiving your ASICS EX89 shoes, carefully remove them from the packaging. Inspect both shoes for any visible defects or damage. Ensure all components, including laces, are present and intact.
2.2 Initial Fitting
Try on both shoes with the type of socks you typically wear. The shoes should feel snug but not uncomfortably tight. There should be about a thumb's width of space between your longest toe and the end of the shoe.
2.3 Lacing
The ASICS EX89 features a standard lace-up closure. Adjust the laces to achieve a secure and comfortable fit across the top of your foot. Avoid lacing too tightly, which can restrict circulation, or too loosely, which can lead to instability.

Proper care will extend the life and appearance of your ASICS EX89 shoes.
4.1 Cleaning
- Surface Cleaning: Use a soft brush or cloth to remove loose dirt from the polyester outer material.
- Spot Cleaning: For tougher stains, use a mild soap solution and a damp cloth. Gently rub the affected area.
- Sole Cleaning: Clean the rubber outsole with a brush and water to remove debris.

5. Troubleshooting
If you encounter any issues with your ASICS EX89 shoes, consider the following:
- Discomfort/Stiffness: New shoes may feel stiff initially. Wear them for short periods to break them in. The footbed is designed to conform over time.
- Sizing Issues: Refer to the size guide in Section 6. Ensure you have selected the correct size for your foot.
- Squeaking: This can sometimes occur due to friction between parts of the shoe or between the shoe and the floor. It often resolves with wear.
- Material Wear: While durable, all materials are subject to wear over time. Follow maintenance guidelines to maximize longevity.
