Let’s start with what NOT to do to your shoes in general:

Avoid the wash: Contrary to popular belief, the washing machine is a no-go zone for any type of canvas/ knit or mesh shoe. Even the gentlest cycles can damage the glue that keeps your shoe together and make your soles look more worn down.
No air: Much like our skin, shoes require decent airflow to enable it to breathe. Never store shoes in plastic.
Overwearing: Constantly wearing a single pair of shoes can irreversibly damage the structure of them, in which case, no amount of cleaning can save it. Rotate your shoe wardrobe often.
Dry feet only: Always dry your feet before wearing shoes- damp/moist feet can cause a multitude of health issues and also causes shoes to get moldy.
Don’t forget to wipe: Mud and liquids should be wiped off as soon as possible, specifically from leather shoes to avoid stains.
Forget the heater: In our previous post on making shoes more comfortable, we suggested you stretch them out using a hairdryer- if you want to keep the shape of your shoes, the reverse is also true. Do not dry your damp shoes near a heat source. Air drying is best.
