A stirrup for saddles. The stirrup includes a pair of side members that extend upwardly from opposing sides of a tread. The tread is provided with a forwardly and downwardly slanted orientation. The orientation of the tread places a rider's foot in a heels-up position in which the rider's heel is above the toes. The heels-up position may be beneficial to professional and experienced riders participating in rodeo events like team roping, barrel racing, or other events in which the rider benefits from being in a forward position over or in front of the saddle. A cross-member extends between upper ends of the side members in a non-parallel orientation relative to the tread. The orientation of the cross-member causes the bottom end of the stirrup to list toward the animal to provide a rider with a more natural position when standing in the stirrups.
