How effective is custom orthotics for plantar fasciitis?

Plantar fasciitis affects the band of tissue under the foot, often causing pain around the heel or arch during loading. An insert can support the arch, spread pressure across the sole and guide motion while you walk. It does not directly repair irritated tissue, and a custom device is not automatically more helpful than every ready-made option. A clinician should consider your foot shape, painful areas, footwear and daily activities before deciding whether it is suitable.

Wear the device in supportive shoes and introduce it gradually so you can notice rubbing, pressure or a change in symptoms. Combine it with a calf and plantar-fascia stretching programme, sensible activity modification and advice about footwear. Keep track of when heel pain appears, such as after rest, during exercise or at the end of the day. If the insert causes new pain, numbness or blisters, stop using it and arrange a fit check rather than forcing your foot to adapt.

Arrange an assessment if heel pain limits walking, persists despite a carefully followed plan or keeps returning when activity increases. Seek prompt medical attention for a hot, markedly swollen or red foot, an inability to bear weight, sudden injury, or new weakness or numbness. These features can point to a problem that needs a different examination.

Could my pain be coming from another part of the heel or arch? What change in walking or pressure is this orthotic intended to make? How should I build up wear, and when should the fit be reviewed? Which stretches, exercises and footwear changes should accompany it?
