How to use: Simply slip your feet into these shoes and tie the laces to a comfortable tightness. They're great for long work shifts. Note: Don't wear them in extremely wet or oily areas for too long as it may affect the slip - resistant feature. Make sure to check the electrical hazard rating before using in relevant workplaces. Maintenance: Regularly clean the shoes with a soft brush and mild soap. Let them air dry. Avoid using harsh chemicals as they can damage the materials.
