Abstract: This invention relates to a stirrup iron (1) comprising a two part construction including a first, fixed part (3), and a second, moveable part (5). The fixed part (3) comprises a body and the moveable part (5) comprises an L-shaped arm pivotally mounted to the fixed part (3).The moveable part (5) is pivotable to and from a first operating position in which a step portion (15) of the moveable part (5) forms a closed loop stirrup, and a second operating position in which the step portion (15) is located below and spaced apart from the fixed part (3) thereby forming a foot-step. The stirrup iron (1) further comprises a releasable locking mechanism, a foot plate (19) mounted on the fixed part (3) and a cam mechanism connecting the foot plate (19) to the moveable part (5). Depression of the foot plate (19) will cause the cam mechanism to act on the moveable part (5) urging it from the second operating position towards the first operating position.
