The SCS3 stirrup pad is equipped with the SCS3 system, which stabilizes positions, depending on riders preference. The SCS3 pad is shaped with a gentle 5 degree backward incline to help keep heels down and achieve a better position. The SCS3 pad is made from two different rubber composites, with the upper part of the rubber being stiffer to form a more effective base for the external soles of the SCS3 boots and shoes. The lower part of the rubber is softer to provide greater impact absorption. The SCS3 pad fits most other stirrups/irons. Material: 100% rubber.
