A steel-toe boot (also known as a safety boot, steel-capped boot, steel toecaps or safety shoe) is a durable boot or shoe that has a protective reinforcement in the toe which protects the foot from falling objects or compression. Safety shoes are effective in keeping the feet of industrial workers safe from sharp and heavy objects while working in factories. Safety footwear now comes in many styles, including sneakers, clogs, and dress shoes. Some are quite formal, for supervising engineers who must visit sites where protective footwear is mandatory.
