When Is Custom Orthotics Recommended for Flat Feet?

Flat feet can be flexible, with an arch appearing when the foot is lifted, or more rigid, with the sole remaining flatter. Many people have flat feet without needing treatment. An assessment looks at your standing posture, walking pattern, shoe wear, joint movement and the location of symptoms. Custom devices are shaped to your foot and may support the arch, guide pressure through the sole and reduce strain on the ankle, knee or other areas. They do not permanently change the foot shape.

Begin with footwear that fits comfortably, has adequate room for the toes and provides suitable support. A clinician may also suggest activity adjustments, calf or foot exercises and a gradual trial of an orthotic. Wear a new device for short periods at first and report rubbing, numbness or worsening pain so its fit can be checked. A custom design is most useful when it matches a specific pressure or movement problem rather than simply being used because an arch looks low.

Arrange an assessment if foot pain keeps returning, one foot changes shape, walking becomes difficult, or symptoms limit work, exercise or daily activities. Seek prompt care after an injury that causes marked swelling, inability to bear weight, new weakness or loss of sensation. Children with persistent pain, frequent trips or a noticeably stiff foot also benefit from evaluation.

Ask whether your symptoms come from foot alignment or another condition, what the examination shows, which non-device options to try first, how to break in an orthotic, and when the fit should be reviewed.
