Used MDC Super Sport Stirrups. New retail price is around $200. From the MDC Stirrup site: High Traction, Greater Support for the Performance Minded Rider. The MDC Super Sport™ features our ultra-low profile, high traction aluminum tread, which delivers more traction, support, comfort and easily releases in a fall. MDC’s advanced tread design does not cut your boots, breeches or saddle leather. Optional traditional width aluminum treads are available. Our ultra-low profile tread is practically invisible in the show ring, allowing all the benefits of our advanced design with the classic lines of traditional stirrups. The MDC Super Sport™ has the same patented design as our MDC Ultimate Stirrup® with lighter weight and a superior tread.
