Foot orthotics are custom-made or pre-fabricated devices designed to support, align, or improve the function of the foot. They are often used to alleviate pain, correct foot deformities, and enhance overall foot mechanics. Common materials include foam, plastic, and rubber, which provide cushioning and stability. These devices can be beneficial for various conditions, such as plantar fasciitis, flat feet, and high arches. By redistributing pressure and improving alignment, foot orthotics can help reduce discomfort and prevent further injury. They are typically recommended by healthcare professionals, including podiatrists and orthopedic specialists.
