Will my child grow out of flexible flatfoot?
The arch height improves in most children up to about age 10, but roughly 15–20% of adults keep a flexible flat foot for life with no consequences. Function, not arch height, is what matters.
Flexible Flatfoot: Why the Arch Disappears and When It Matters
Flexible flatfoot is a flat foot whose arch returns as soon as body weight comes off it — on tiptoes, when sitting, or when the big toe is lifted. It is the commonest form of flatfoot, is usually painless, and in the absence of symptoms requires reassurance and observation rather than insoles, braces, or surgery.

How it is recognised
Two bedside tests settle the diagnosis in seconds. The tiptoe test: when the child rises onto the toes, the heel swings inward and the arch reappears. The jack test: passively extending the great toe tightens the plantar fascia and lifts the arch. A foot that passes both is flexible.
The subgroup that does need treatment
Flexible flatfoot with a tight gastrocnemius behaves differently. Limited ankle dorsiflexion with the knee straight forces the midfoot to break down at every step, producing arch or lateral-column pain in adolescence. This subgroup responds to a structured daily calf-stretching programme, and, when stretching fails and pain persists, to gastrocnemius recession with or without a calcaneal lengthening.
Practical management
Asymptomatic: no treatment, normal shoes, unrestricted sport, review only if symptoms appear. Symptomatic: daily calf stretches held 30 seconds and repeated three times on each side, shoes with a firm heel counter, weight management where relevant, and an off-the-shelf orthosis trialled for pain relief. Escalate to a specialist when pain limits sport or school after three to six months.
Frequently asked questions
Should my child wear special shoes?
No. Corrective or 'orthopedic' shoes have never been shown to alter arch development. A comfortable, well-fitting shoe with a firm heel counter is enough.
