Wearing close-toed shoes provides protection to the feet from potential hazards such as chemical spills, falling objects, or sharp objects on the floor. Sandals and open-toed shoes leave the feet exposed and vulnerable to these risks, while going barefoot (no shoes) completely disregards safety precautions. Therefore, close-toed shoes are the most appropriate choice for wearing in the laboratory.Rate this question:
