The MDC Intelligent Stirrups are a revolutionary new stirrup design that positions your stirrups where YOU want them. Riders can now select any of three preset stirrup positions: traditional, 45 degrees or 90 degrees. You can customize your stirrups to the setting that best suits you, your horse and your riding application. This Feature is a First in Modern Stirrup Technology! The preset angle improves leg, calf and foot position, relieves pressure on hips, knees and ankles, as well as reducing leg burns.
