Wondering whether children orthotics for flat feet are actually worth it? A 6-month cohort study published in Prosthetics and Orthotics International in May 2026 followed 100 children and adolescents with developmental flatfoot and gives parents a much clearer answer than the usual “wait and see”. The short version: for kids with painful flat feet, combining orthotic insoles with structured rehabilitation produces meaningful gains in both pain and function over six months.
Are flat feet in kids actually a problem?
Most very young children have flexible flat feet — it is a normal part of foot development. The arch on the inside of the foot typically starts to form from age four and is usually developed by age six. As a result, most flat feet you spot in a three-year-old do not need any intervention at all.
The picture changes when (1) the flat foot is painful, (2) the child is fatigued faster than peers during sport or play, (3) the foot is rigid rather than flexible, or (4) there is a clear asymmetry between the two feet. In those cases, children’s orthotics for flat feet — alongside loading exercises — can change the trajectory.
When to wait, when to act
“Wait and see” is reasonable for a painless, symmetrical, flexible flat foot in a child under six. However, if your child reports foot or leg pain after activity, avoids running games at school, complains of tiredness in the calves or knees, or has visibly inward-rolling ankles, that is the cue to have the foot assessed by a podiatrist. Catching it earlier means a shorter intervention.
Inside the May 2026 cohort study
The May 2026 study split 100 children aged 6–18 with developmental flatfoot into two groups: 50 received orthotic insoles plus rehabilitation; 50 received rehabilitation alone. Both groups were measured at 12 weeks and again at 24 weeks against four outcomes: pain (Visual Analog Scale), function (Foot and Ankle Ability Measure), plantar pressure distribution and navicular drop — a clinical measure of arch collapse.
The orthotics-plus-rehab group showed superior improvement on all four measures compared with rehab alone. The combined approach changed pressure distribution under the foot and reduced navicular drop, while also improving the pain and function scores that matter most to families. Critically, the gains held at the 24-week follow-up — so the effect is not purely a short-term comfort response.
What “orthotics plus rehab” looks like for an 8-year-old
At our Gold Coast clinic, the children’s protocol starts with a full biomechanical assessment, a video gait analysis and a short scan of both feet. From there we prescribe either a flexible soft orthotic or a hard 3D-printed orthotic matched to the child’s foot type and shoe wardrobe. The orthotic provides daily structural support without locking the foot into one position.
Alongside the orthotic, we run a graded loading plan: foot-intrinsic strengthening (short-foot exercises, towel scrunches), calf and arch stretches where relevant, and balance work to build the kinaesthetic control children need. Sessions are short and game-based for younger kids and treated like a sports programme for older teens.
What we re-measure at 12 and 24 weeks
Mirroring the 2026 study, we re-measure pain, function and navicular drop at three and six months. That gives parents a clear, objective answer to “is this working?” rather than a vague clinical impression. If progress has stalled by week 12, we adjust the orthotic prescription or the loading plan rather than continuing on autopilot.
For wider context, the Australian Podiatry Association on children’s feet outlines the conditions that benefit from early assessment.
Children’s orthotics for flat feet — when to book
If your child has painful flat feet, is avoiding sport because of foot fatigue, or has visibly collapsing arches under load, an assessment is the right next step. Our Gold Coast podiatrists see children from age four and design interventions that fit family life — including school-shoe and sport-shoe orthotic options that don’t make your child feel different from peers.
Frequently asked questions
At what age should I worry about my child’s flat feet? Painless, symmetrical, flexible flat feet in children under six are usually a normal stage of development. Pain, fatigue, rigidity, or visible asymmetry at any age warrants an assessment.
Will my child grow out of flat feet? Many children do — but not all, and pain is not “normal growing up”. If pain is part of the picture, an orthotic-plus-rehab plan supports the development pathway rather than waiting for it to resolve on its own.
How long does my child need to wear children’s orthotics for flat feet? Most children wear orthotics during their growth years, with re-assessments every 6–12 months as feet change. We aim to reduce reliance over time as the foot’s intrinsic strength improves.
Are children’s orthotics covered by private health? Yes — most extras-level private health funds include a podiatry and orthotics allowance. We process HICAPS on the spot for 12 major Australian funds.
