Please read this before acting on anything you read on Best Insoles for Flat Feet.

1. Not medical advice

Our guides explain how over-the-counter insoles and arch supports are designed and who they tend to suit. They are general information, not a diagnosis, treatment plan or substitute for advice from a doctor, podiatrist or physical therapist who has examined you.

2. What insoles can and cannot do

Arch-support insoles are designed to support the arch and spread pressure across the foot, which many people find more comfortable. They do not permanently change the shape of the foot, and they are not a cure for any condition.

3. When to see a professional

• Pain that is severe, gets worse, or lasts more than a few weeks.
• Pain, swelling or a change in the shape of one foot only.
• Numbness, tingling, a wound that does not heal, or diabetes or poor circulation.
• A child with foot pain, limping or very stiff feet.

4. Your responsibility

If you start using an insole and pain increases, stop and seek advice. Follow the manufacturer’s instructions for fit and break-in.
