Greaves are protective armor pieces designed to shield the lower legs, typically covering the area from the knee to the ankle. They were widely used in ancient and medieval combat to protect against slashes, stabs, and other injuries during battle. Greaves were commonly made from materials like bronze, steel, or hardened leather and were shaped to fit the leg's contours. They were secured with straps, buckles, or hinges to ensure they stayed in place during movement. Used by warriors in many cultures, including Greek hoplites, Roman legionaries, and medieval knights, greaves were an essential component of combat attire, balancing protection and mobility. Modern versions are used in sports or reenactments for safety and authenticity.
