What is the primary purpose of the medial flange on an orthotic?

The primary purpose of the medial flange on an orthotic is to support the arch. This structure is specifically designed to enhance stability and provide proper alignment for the foot. By doing so, it helps distribute weight evenly across the foot and supports the natural architecture, which can alleviate discomfort and improve overall function.

The medial flange also plays a crucial role in accommodating or correcting various foot abnormalities associated with the arch. Proper arch support is essential for maintaining a neutral position in the foot, which is particularly important for individuals with flat feet or other conditions that require additional support to promote a healthy gait.

While resisting foot slippage laterally and controlling rearfoot supination are important aspects of orthotic design, these functions are not primarily attributed to the medial flange itself, but rather to other components of the orthotic structure. Thus, the focus on supporting the arch is what truly defines the purpose of the medial flange.
