On the traditional saddle the stirrup is sideways. When you put your foot ino it you have to twist the stirrup and the fender with your foot, thus putting stress on the ankle. The Stirrup Strait will alleviate the twisting! When using the Stirrup Straight the stirrup is off center, this puts the fender and stirrup forward and helps alleviate stress in the knee. Easier on both the knees and ankles! Solid steel construction with electric powder coating. Brown. Available in 2 1/2" and 3" size.
