Instructions
Place the stirrup on the ground so it is standing upright.
With your riding boots on, insert your foot into the stirrup so the ball of your foot is resting on the flat plate of the stirrup.
Use a ruler to measure the gap between your boot and the stirrup frame on each side of your foot. These gaps should be approximately three-quarters of an inch.
Verify both stirrups hang at even lengths from the saddle on both sides. After mounting, check the angle between the thigh and lower leg. The legs should be bent at a comfortable angle, both feet securely in the stirrups.
