Millions of Americans wear ankle-foot orthotic devices for protection, pain relief, and deformity correction. Inquiries about off-the-shelf and custom devices are a common reason for evaluation with a foot and ankle surgeon or general orthopaedic surgeon. Despite limited high-quality evidence for their use, these devices can have a notable clinical impact on physical function. An up-to-date understanding of orthotic device options and their appropriate use in managing musculoskeletal pathologies applies to all orthopaedic providers. This review aims to categorize orthosis types and provide specific device recommendations for common adult conditions such as flatfoot, cavovarus foot, and ankle instability. Collaboration with a certified orthotist can help patients achieve functional and recreational goals with the use of appropriately designed and applied orthoses.
