How effective is custom orthotics for achilles tendinitis?

The Achilles tendon transfers force from the calf to the heel. Foot position, footwear and walking or running habits can change how that force is distributed. An orthotic is shaped for your foot and placed inside footwear to influence contact and loading. It may make standing or walking more comfortable, but it does not heal the tendon by itself. Tendon capacity usually needs gradual, planned loading, with the amount adjusted to symptoms and function.

A clinician should examine your tendon, footwear, walking pattern and activity goals before prescribing a device. Introduce the orthotic gradually and check for rubbing, pressure points or a change in knee, hip or back discomfort. Pair it with the recommended calf and ankle programme rather than replacing exercise. Use supportive footwear that fits the device, and arrange review if pain remains unchanged or your walking becomes less natural.

Seek prompt assessment after a sudden snap, a visible change in the tendon, or difficulty pushing off or walking. Contact a clinician for increasing swelling, redness, warmth or pain that is not settling. Stop using an orthotic that causes a persistent blister, numbness or marked pressure until it has been checked and adjusted.

What is contributing most to my tendon load? Should I use an orthotic for walking, sport or both? How quickly should I introduce it? Which strengthening exercises are appropriate now? What signs mean the device needs adjustment or the diagnosis needs review?
