A stirrup has a pair of arms, an eye on the arms for receiving a strap, and a footrest on the arms for supporting the foot of a rider. A cylinder/plunger assembly at each end of the footrest defines its travel between a retracted position and an extended position. A spring acting on the plunger in each cylinder urges the footrest toward the retracted position, such as to provide shock absorption for downward pressure exerted by the foot of a rider.
