To wear these shoes, just slip your feet in like you would with any regular shoes. They're suitable for various casual and semi - formal occasions. When it comes to maintenance, use a soft brush to remove dirt regularly. For the leather or suede upper, use appropriate leather or suede cleaners. Avoid exposing them to excessive water as it might damage the material. Let them dry naturally if they get wet. As for the sole, there's no special care needed, but keep an eye on the wear and tear. If you notice the sole getting too thin, it might be time to consider getting them resoled.
