The narrow and strong mono stirrup leathers are made of good quality soft leather. The mono stirrup leather is shorter than the standard stirrup leather because it doesn't double under your legs or saddle pad. As a result, your legs are even closer to the horse so that you can adjust the aids even finer. The belt can be adjusted at the bottom in no less than 7 different positions. The buckle is protected by a leather cover so that your footwear is not damaged. Due to their nylon insert, they cannot extend even with heavy use. Passier has looked closely at a solution so that the stirrups can be raised when the saddle is not in use. They also made a hole in the top of the stirrup leather for this purpose.
