What to Expect from Custom Orthotics for Tarsal Tunnel Syndrome

Tarsal tunnel syndrome involves irritation or compression of the posterior tibial nerve as it passes behind the inner ankle. Burning, tingling, numbness, or aching may travel into the sole or toes. If foot posture increases tension or pressure in this area, an orthotic may support a less aggravating position and spread load across the foot. It cannot directly release a compressed nerve, so the cause and severity of symptoms still guide treatment.

The assessment may include sensation, strength, reflexes, walking pattern, ankle movement, and shoe fit. Start the orthotic for limited periods and inspect the skin and symptoms afterward. Use footwear with a firm base and enough depth; tight shoes can add pressure around the ankle. Record whether tingling changes with standing, walking, or rest. Your plan may also include activity changes, exercises, medication, or further nerve evaluation depending on the findings.

Arrange medical review for increasing numbness, burning that interferes with sleep, worsening balance, or weakness in the foot. Seek urgent care for sudden loss of strength, rapidly spreading numbness, a cold or discoloured foot, or severe swelling after an injury. New symptoms should not be attributed to the orthotic without checking the fit and the underlying diagnosis.

Ask what may be compressing the nerve, how to judge whether the orthotic is helping, whether nerve testing is needed, and which shoes or activities should be avoided.
