Painting the rubber soles of your shoe is an easy way to personalise them. However, you cannot use just any paint. The sole of your shoe comes into contact with surfaces every time you use it. The constant friction your rubber soles go through can be harsh enough to crack your paint. A durable option is painting your rubber soles with tire paint. Tire paint is made for rubber tires and is durable. In addition, tire paint comes in a variety of colours.
Apply the paint with a tire paint pen. A tire paint pen is easier to control and use than a bucket of paint and paintbrush.
Decorate your shoe with the paint pen as desired. Allow the paint to dry completely.
Apply a second coating of paint if necessary to cover the rubber completely. Allow the paint to dry completely.
