Greaves are a type of armor designed to protect the lower legs, specifically the area from the knee to the ankle. Typically crafted from metal, leather, or a combination of materials, greaves were an essential part of ancient and medieval combat gear, offering vital protection in battle against strikes and projectiles. They were often anatomically shaped to fit snugly around the legs and secured using straps, buckles, or hinges. Commonly used by soldiers, knights, and warriors across cultures, greaves were a key element of a full suit of armor, ensuring mobility while safeguarding against injury. Modern versions of greaves can also be seen in some sports and martial arts for protective purposes.
