Orthotic inserts help treat corns by redistributing pressure away from high-friction points on the toes and feet, reducing the mechanical forces that cause skin to thicken. Custom or well-fitted over-the-counter orthotics can improve foot alignment and offload bony prominences, allowing the painful central core of a corn to gradually diminish. They are particularly useful when corns are related to foot deformities such as hammer toes or abnormal gait mechanics. While orthotics do not remove existing thickened skin, they are a key long-term strategy to prevent recurrence when combined with proper footwear and periodic lesion care.
