Clean your shoes at least once a month. Brush off dirt. Remove the insoles. Soak the shoes and the insoles in soap water, then rinse them. Allow to air-dry.

You can alternate two pairs of shoes rather than wearing the same pair everyday. 

Wear the shoes properly. Don’t step on the back of shoes. 

Wear shoes of the right size. Make sure that your toes have wriggle room. Leave a finger’s space between the heel of the foot and the shoes.
