The MDC Classic Jumper stirrup features a traditional look with a classic design, but has the advanced benefits of the MDC 'sure grip' aluminum tread. MDC is the World Leader in patented, adjustable top high tech stirrups. The MDC Jumper Classic model focuses our innovative design concepts on the tradition based rider. It features more traction, more stability and more comfort in an ultra-low profile base that is lighter than standard fillis irons. This mixed metal stirrups (stainless steel and aluminum) will weigh less than traditional fillis stirrups and hang true for better stirrup retrieval than all aluminum models. This stirrup has the MDC wide tread, but can be converted to a traditional width aluminum tread (sold separately), but you won't want to switch! The feel of a wide tread is fantastic, but up until now, no one has made available a wide tread stirrup that conforms visually to those who prefer a traditional stirrup design. Due to the very low profile of our tread, this stirrup can be worn in all other rings: hunters, equitation and dressage. Flex stirrup.
