Non-surgical treatment of flatfoot aims at symptoms, not at arch shape. The three interventions with real value are a daily gastrocnemius stretching programme, footwear with a firm heel counter, and an orthosis used for pain relief in a symptomatic foot. A painless flexible flat foot needs none of them.
Gastrocnemius tightness is the single most modifiable driver of arch collapse. Stretch with the knee straight, heel flat on the floor, leaning into a wall, holding 30 seconds, three repetitions per side, twice daily. Consistency over three months is what produces measurable gains in dorsiflexion; sporadic stretching does nothing.
Prefabricated and custom orthoses perform similarly for pain relief in most studies, and neither changes arch height permanently. Use them when a symptomatic foot needs comfort during long days or sport, review at three months, and stop them if they are not helping. Do not prescribe them to 'build an arch' in a painless child.
Consider surgical referral when pain persists beyond six months of genuine conservative treatment, when it limits school or sport, when the deformity is rigid, or when it is progressing in a neuromuscular child. Modern reconstruction is joint-sparing: calcaneal lengthening, gastrocnemius recession, Cotton osteotomy, and internal bracing, selected to the individual foot.
A painless flexible flat foot does not need fixing, and no insole, exercise or shoe permanently raises the arch. A painful flat foot can almost always be fixed in the sense that matters — pain relieved and function restored — with calf stretching, supportive footwear and an orthosis, and with joint-sparing surgery such as calcaneal lengthening in the minority who do not respond.
Calf stretching with the knee straight is the priority. Heel raises, short-foot exercises and single-leg balance work strengthen the supporting muscles and reduce pain, though they do not permanently change arch height.
For most symptomatic flexible flat feet, a good prefabricated device performs as well. Custom devices are justified for marked deformity, neuromuscular feet, or when an off-the-shelf device cannot be fitted comfortably.
