What to expect from custom orthotics for Achilles tendinitis

Achilles tendinitis, also called Achilles tendinopathy, affects the tendon connecting the calf muscles to the heel. Custom orthotics are shaped to your foot and placed inside suitable shoes. Depending on your alignment and walking pattern, they may redistribute pressure and alter the motion that loads the tendon. They support a broader rehabilitation plan; they do not directly repair the tendon or replace progressive calf strengthening.

Wear the orthotics for short periods at first, then increase use as your feet and calves adapt. Check for rubbing, new pressure points or a clear increase in tendon pain. Use shoes with enough depth and a stable sole, and bring your usual footwear to the fitting review. Continue the exercise and activity plan provided by your clinician, adjusting load if walking or sport causes a sustained flare.

Arrange review if the orthotics cause blisters, numbness, persistent arch pain or worsening Achilles symptoms despite a careful break-in. Seek urgent care for a sudden snap, marked swelling, bruising or difficulty pushing off or walking, as these can signal a more serious tendon injury.

Ask what feature the orthotics are intended to change, how quickly to increase wear, which exercises remain appropriate, and when the fit should be reassessed.
