A
spur is a metal tool designed to be worn in pairs on the heels of
riding boots for the purpose of directing a
horse to move forward or laterally while
riding. It is usually used to refine the
riding aids (commands) and to back up the natural aids (the leg, seat, hands and voice). The spur is used in many equestrian disciplines. There are rules in most equestrian organizations about spur design, use and penalties for using spurs in any manner that constitutes
animal abuse.
