Insoles for arch pain: what to know

An insole sits inside the shoe to cushion the foot and alter how force travels from the heel through the arch. A comfortable, appropriately shaped device can make walking or standing easier when the arch is overloaded. It does not repair every source of pain, and a rigid or poorly fitting insole can create pressure in a new area.

Arch pain can occur with flat feet or with irritation of the plantar fascia. Look at the pages on [Flat Feet](/conditions/flat-feet/) and [Plantar Fasciitis](/conditions/plantar-fasciitis/) to understand these different patterns. Your symptoms are also described in [Arch Pain](/symptoms/arch-pain/).

Choose footwear with enough depth and a stable sole. Introduce a new insole for short periods, then increase wear if the foot remains comfortable. Stop using it if it causes numbness, rubbing, marked pressure, or worsening pain. A clinician can check your walking pattern, shoe fit, ankle movement, and tenderness before recommending a prefabricated option or [Custom Orthotics](/treatments/non-surgical-orthopedics/custom-orthotics/). Gentle calf and foot exercises may also be useful when matched to your assessment.

Arrange an assessment if pain persists despite changing activity and footwear, keeps returning, or limits normal walking. Seek prompt care for sudden severe pain, inability to bear weight, significant swelling, redness and warmth, fever, or new weakness or numbness. These features need evaluation rather than an insole trial alone.

Ask what is driving the arch pain, whether your foot posture changes the advice, and whether an off-the-shelf insole is suitable. You can also ask how long to trial it, which signs mean it should be removed, and whether exercises or other treatment should accompany support.
