Developed by Herm. Sprenger, the Bow Balance stirrups keep the rider's legs in the correct position, such as the knees and heels. Furthermore, the System 4 feature allows for flexible movement in four directions (front, back, left, and right), accommodating all foot movements and providing a comfortable ride. It also reduces the impact on the cartilage and ligaments of the foot. In addition, the upper part of the stirrup is made heavier and the lower part lighter, reducing the fluttering when the stirrup comes off. The step area has also been widened, increasing stability. By using two types of rubber grips, hard on the outside and soft on the inside, it excels in shock absorption. Sprenger Bow Balance stirrups, in a black and blue design, offer excellent grip. - Brand: Sprenger - Color: Black - Model Name: Bow Balance Equestrian Equipment Retail Price: ¥46,200 I am selling these because I switched to different stirrups. There have been no falls or drops. There is some dirt that cannot be removed, but there is no paint peeling. Thank you for viewing.
