What is the primary function of a foot orthosis?

The primary function of a foot orthosis is to provide support, alleviate pain, and improve foot function. Foot orthoses are custom-made or pre-fabricated devices that aim to enhance the biomechanical efficiency of the foot, addressing issues such as overpronation, supination, or other alignment problems. By supporting the arches of the foot and redistributing pressure, they help reduce discomfort associated with various conditions, such as plantar fasciitis, flat feet, and arthritis.

In addition to providing structural support, foot orthoses can help improve overall function by promoting a more natural walking pattern, which can lead to better stability and balance. They are designed to accommodate the unique contours of an individual’s foot, ensuring a proper fit that optimally supports the patient's specific needs, thus enhancing comfort and functionality. While they may contribute to performance improvement in certain contexts, such as athletics, their primary purpose remains focused on support and pain management.
