Proper use and care are key to making sneakers last longer, including using waterproof spray before use to enhance water resistance, and regular use of shoe polish or conditioner to keep the uppers soft and waterproof. In addition, it is also important to replace the insoles regularly, because the insoles will become thinner and deformed over time, affecting comfort and foot support. ‌

Methods for maintaining sneakers include:
1. Use a waterproof and stain-proof spray. Spray a layer of protective fluid on the surface of the sneakers to form a protective layer to prevent water and stains. ‌
2. Toothpaste and toothbrush. Carry toothpaste and a toothbrush with you for instant cleaning of small stains on your shoes.
3. Avoid wearing it on rainy days. Rainy days will turn white shoes yellow and dirty, so you should try to avoid wearing white shoes on rainy days.
4. Clean immediately after returning home. Gently wipe the dirty area with a damp towel or paper towel, then place in a cool, dry place.
5. Avoid using a washing machine for cleaning. The rotation force of the washing machine is strong, which may cause the shoes to deform and deteriorate the material.
6. Cleaner selection. You can use a special white shoe cleaner or a natural recipe like baking soda and white vinegar. ‌
7. Antifouling spray. Use anti-stain spray after cleaning to prevent water, stains and scratches. ‌

Precautions for maintaining sneakers include:
1. Do not clean frequently. Generally speaking, cleaning once every two to three months is enough. Excessive cleaning may damage the structure and surface material of the shoes.
2. Do not use toothpaste to clean sneakers. Toothpaste is corrosive to the surface material of sports shoes and may cause damage to the uppers.
3. Do not soak for a long time. Some materials of sports shoes are not waterproof, and long-term immersion in water may cause the material to soften and deform.
4. Do not use a hair dryer to dry. Heat will cause the water to evaporate quickly, causing parts of the shoe's structure to dry out.
