Safety stirrups with hinged legs mounted on a metallic chain covered with non-skid rubber. The UMS 6 System (international patent in process) offers an unequalled comfort of movement to the rider. The hinged legs follow independently from each other the rider foot position: forward, backward and side-to-side and offer a better resistance against pressure and impacts than fixed legs. Especially recommended for jumping. Comes in a protection cover with a pair of grey rubber stirrup pads and a pair of exchangeable non-skid metallic treads.
