Flat Feet (Fallen Arches) — Podiatry in Canary Wharf, London

No. The NHS confirms flat feet are usually harmless and need no treatment when they cause no symptoms. Many people have flexible flat feet for life without problems. Treatment is only worthwhile if your feet cause pain, aching or fatigue, or are contributing to ankle, knee or lower-back problems — that is when an assessment helps.

No. Orthoses do not permanently reshape the arch; they support the foot, help control overpronation and offload strained tissues. The evidence is that they can ease symptoms for many people rather than guarantee a cure. We use them alongside footwear advice and foot and tibialis posterior strengthening as part of a wider plan.

Yes. An arch that flattens in adulthood often points to tibialis posterior tendon dysfunction (adult-acquired flatfoot), where the tendon supporting the arch weakens or tears. It typically causes inner-ankle pain and swelling and tends to progress. Early biomechanical assessment matters, because orthotic support and rehabilitation aim to ease symptoms and may slow progression.

See a podiatrist promptly if an arch flattens suddenly, only one foot is affected, or your foot or inner ankle becomes painful, swollen, stiff, weak or numb, or walking becomes difficult. Seek same-day care for signs of spreading infection — spreading redness, heat, fever or a hot, painful, swollen foot. People with diabetes or poor circulation should have any new foot change checked quickly.
