What may cause an orthotic to rock on the anterior edge of the post?

When considering the stability of an orthotic, tapering plays a crucial role in its function and fit within the shoe. If the orthotic is tapered incorrectly, it can lead to a rocking motion, particularly on the anterior edge. Tapering is the process of gradually reducing the width of the orthotic, which is essential for proper alignment and distribution of weight during movement.

If the taper is not executed correctly, the orthotic can create an imbalance, causing the foot to pivot or rock on the anterior edge instead of providing a stable base. This can affect gait mechanics and comfort.

Other factors like angle misalignment, excessive heel height, or an excessively short anterior end could cause discomfort or improper fit but are less directly associated with the specific rocking motion on the anterior edge like an improper taper would be. Thus, understanding the importance of tapering is vital for ensuring that the orthotic functions as intended, providing a solid platform for the foot.
