I am selling Sprenger brand safety stirrups. These safety stirrups open in the event of a fall by applying pressure so that the rider's foot does not get caught in the stirrup, dragging the rider and causing serious injury. Stirrup inserts have a non-slip profile to prevent the riding boot from slipping in the stirrup. In addition, you can get stirrup inserts and elastic rings in bright colors and customize your stirrups anytime.
