Orthotics effectively address many rearfoot issues by supporting alignment, reducing stress, and cushioning, including Plantar Fasciitis, Achilles Tendinitis, Posterior Tibial Tendon Dysfunction (PTTD), flat feet (overpronation), high arches, bursitis, and problems from arthritis or diabetes, helping with pain, stability, and proper foot mechanics. They work by controlling abnormal motion, supporting arches, and re-aligning the heel to relieve pressure on inflamed tissues
