How long do custom orthotics take to work for Achilles tendinitis?

The device is intended to alter pressure and motion through the foot, which can reduce strain reaching the heel and Achilles tendon during walking. Early sensations may include unfamiliar pressure or mild muscle fatigue. That does not by itself show whether the orthotics will help. Tendon tissue also needs time to settle, and orthotics usually work best as one part of a plan that may include activity adjustment and progressive calf rehabilitation.

Begin with the wear schedule supplied by the clinician or fitter, then build up gradually if your feet tolerate it. Use the orthotics in suitable shoes with enough room and stable support. Track walking comfort, morning stiffness, and pain during activity rather than judging them after one wear. Do not push through increasing pain; contact the treating clinician if the fit causes rubbing, numbness, new pressure points, or a marked change in your gait.

Arrange a review if symptoms are worsening, the orthotics remain uncomfortable after a reasonable adjustment period, or progress has stalled despite following the plan. Seek prompt assessment for a sudden pop, inability to push off, substantial swelling, or difficulty bearing weight, because these features may need a different evaluation. Background information is available on [Achilles Tendinitis](/conditions/achilles-tendinitis/).

Ask how quickly to increase wear, which shoes are appropriate, and what tendon-loading exercises should accompany the orthotics. Ask when a fitting check is expected and which changes would mean the device needs adjustment.
