How effective is custom orthotics for shin splints?

Shin splints, often called medial tibial stress syndrome, involve pain along the inner border of the shin linked with repeated loading. An orthotic can influence how the foot rolls and how pressure travels up the leg. That change may be useful when foot mechanics contribute to symptoms, but it cannot correct a sudden increase in running, hard surfaces, worn shoes or weak load tolerance by itself. The cause of shin pain should be assessed before relying on an insert.

Introduce the device gradually in suitable shoes and avoid making several major training changes at the same time. Reduce or replace the activity that provokes pain, then build walking, calf strength and impact in stages guided by symptoms. Note whether pain appears during exercise, later that day or the next morning. Stop and arrange a fit review if the orthotic causes arch pressure, blisters, altered gait or pain in a new location.

Book an assessment if pain is localised to one small spot, occurs at rest or at night, persists despite reducing impact, or makes you limp. Seek prompt care for sudden severe pain, marked swelling, inability to bear weight, numbness or weakness. These signs can require assessment for an injury other than routine shin splints.

Does my pain pattern fit shin splints, or should a bone stress injury be considered? What foot or leg movement is the orthotic intended to change? Which activities can I continue? How should I progress strength and impact, and what symptom response means I should step back?
