Abstract: A step extension for a stirrup is comprised of a top plate for attaching on top of a step member of the stirrup, and a bottom plate for attaching to the bottom of the step member. Fasteners connected between the top and bottom plates secure them to the step member. The top plate has a rear extension for providing better foot support and improving stirrup control. The rear extension extends between an outer portion of the step member and the mid portion of the step member. The top plate has an inner portion which is devoid of any extension, so that its rear edge terminates generally flush with the rear edge of the step member. The lack of a rearward extension on the inner portion of the top plate avoids locking the rider's foot in the stirrup when the rider falls off.
