What is one key component of a custom foot orthotic?

A key component of a custom foot orthotic is arch support. This feature is crucial because it helps to maintain proper foot alignment and distribute body weight evenly across the foot. The arch of the foot plays a significant role in absorbing shock and providing stability during movement. Personalized arch support in a custom orthotic is designed based on an individual's foot shape and arch height, ensuring that it addresses specific biomechanical needs.

Correct arch support can alleviate discomfort and prevent conditions related to foot misalignment, such as plantar fasciitis or overpronation. While cushioning, heel padding, and the toe box can enhance comfort and provide additional benefits, the primary function of custom foot orthotics is to support the arches effectively, making it the central component in their design and function.
