Every week, at least one parent asks me the same question: should kids wear orthotics for flat feet? Usually the question comes after a visit to a pediatrician or podiatrist who recommended insoles. The parent feels caught between wanting to do the right thing and a nagging sense that their child's feet might just need time.
I've worked with hundreds of children who have flat feet over the past 15 years, and my position on orthotics is nuanced. They are not always wrong, and they are not always right. The answer depends on your child's age, the type of flat foot, whether there is pain, and what else you've tried. In this post, I'll share what I tell parents in my practice so you can make a more informed decision for your child.
What Flat Feet Actually Look Like in Children
Flat feet means the arch of the foot sits lower than typical, sometimes touching the ground completely when your child stands. In toddlers and preschoolers, this is almost always normal. Fat pads under the arch make most young feet look flat even when the underlying bone structure is developing just fine.
By around age 5 or 6, most children develop a visible arch. According to the American Academy of Pediatrics, flat feet in children under 6 rarely need any intervention. The arch forms gradually as the muscles, ligaments, and bones of the foot mature. If you're not sure whether your child's feet are genuinely flat, my simple flat feet home test can help you assess what you're seeing.
There are two types of flat feet worth distinguishing. Flexible flat feet means the arch appears when your child stands on tiptoes or sits with feet dangling, but disappears when standing. Rigid flat feet means the arch is absent in all positions. The type matters a great deal when deciding whether orthotics are appropriate.
What Kids Orthotics for Flat Feet Actually Do
Orthotics are custom or prefabricated insoles placed inside a child's shoe. They sit under the arch and are designed to support the foot in a more neutral position during standing and walking. Some are rigid, some are semi-flexible, and some are soft cushioned inserts sold over the counter.
Here is what orthotics can do:
Reduce foot and leg pain in children who have symptomatic flat feet.
Provide temporary support during high-activity periods like sports seasons.
Redistribute pressure across the foot to reduce discomfort in specific areas.
Help children with rigid flat feet or underlying conditions (like cerebral palsy or hypermobility syndromes) maintain better alignment for daily function.
Here is what orthotics cannot do:
Permanently change the structure of your child's foot or "build" an arch.
Strengthen the muscles that support the arch.
Replace the need for active movement and foot exercise.
A 2022 systematic review published on PubMed found limited evidence that foot orthoses change long-term outcomes for children with flexible flat feet. The review noted that while orthotics can reduce short-term pain, they do not appear to alter the natural development of the arch. This aligns with what I see in practice: orthotics manage symptoms, but they don't fix the underlying issue.
When I Do Recommend Orthotics for Children
I'm not against orthotics. There are genuine situations where they make sense. If a child in my practice meets certain criteria, I'll suggest they see a podiatrist for a fitting. Those situations include:
Persistent pain. If your child complains of foot pain, arch pain, or leg pain during or after physical activity, and this has been going on for more than a few weeks, orthotics can provide relief while you work on strengthening.
Rigid flat feet. If the arch never appears in any position, the foot may have a structural difference that exercises alone won't address. A pediatric orthopedist or podiatrist should evaluate rigid flat feet.
Underlying conditions. Children with hypermobility, Down syndrome, cerebral palsy, or other neuromuscular conditions often benefit from orthotics as part of a broader support plan.
Compensation patterns. If flat feet are causing knock knees, ankle rolling, or gait problems that haven't improved with exercises after 3 to 6 months, short-term orthotic use can help break the cycle while the muscles catch up.
In these cases, I view orthotics as a tool, not a solution. They support the foot while the real work (strengthening, movement, proper footwear) happens alongside them.
Orthotics vs Exercises for Children: Why I Start with Movement
For the majority of children with flexible flat feet, I recommend exercises first. The reasoning is straightforward: if the arch is present but weak, the muscles that lift and hold that arch need training, not a crutch.
Think of it this way. If your child had weak core muscles and slouched at the dinner table, you wouldn't strap them into a rigid brace and call it solved. You'd work on building core strength so their body could hold itself up. Feet work the same way. The arch is supported by the tibialis posterior, the peroneal muscles, and the small intrinsic muscles of the foot. These muscles respond to exercise.
In my practice, children who commit to a regular foot strengthening routine typically see visible improvement in arch height and foot alignment within 8 to 12 weeks. Exercises like the Bear Paw Shuffle and Tiptoe Trolley Squat specifically target the muscles that lift the arch. They're playful enough that kids actually enjoy doing them, which matters because consistency is what drives results.
There's another reason I lean toward exercises: orthotics can create dependency. When a child wears insoles that hold the arch in place, the muscles that should be doing that job get less work. Over time, the muscles can weaken further, making the child more reliant on the orthotic rather than less. I've seen children who wore orthotics for years and showed little improvement once the insoles were removed, because the foot muscles never had to develop strength on their own.

How Shoes Affect Flat Feet (and Whether They Replace Orthotics)
Footwear plays a bigger role in flat feet than many parents realize. Stiff, overly supportive shoes can have a similar effect to orthotics: they do the work that the foot muscles should be doing. On the other end, completely flat, unsupportive shoes worn all day can leave a developing foot without any proprioceptive feedback.
The sweet spot for most children with flat feet is a shoe that is flexible, has a wide toe box, and sits close to the ground. These features allow the foot muscles to engage naturally while still protecting the foot. I cover this in detail in my post on choosing the right shoes for kids' feet, and my barefoot shoes for kids guide explains why minimalist footwear is worth considering for children with flexible flat feet.
Barefoot time at home is equally important. Every minute your child spends barefoot on a varied surface is an opportunity for the foot muscles to work. Grass, sand, textured mats, and even just a hardwood floor provide the kind of sensory input that encourages the intrinsic foot muscles to fire. As I discuss in my children's foot development guide, the early years are a critical window for building the foundation of strong, adaptable feet.
Should Kids Wear Orthotics for Flat Feet? A Decision Framework
If you're trying to decide whether your child needs orthotics, here is the framework I use with families in my practice:
Step 1: Determine the type of flat foot.
Ask your child to stand on tiptoes. If the arch appears, the flat foot is flexible. If it does not, consult a pediatric orthopedist or podiatrist to assess whether the flat foot is rigid or structural.
Step 2: Check for pain.
If your child has no pain, no tripping issues, and no difficulty with physical activity, the flat feet are very likely part of normal development. Exercises and appropriate footwear are the right approach. Orthotics are not needed.
Step 3: Try exercises for 8 to 12 weeks.
If there is mild discomfort or you want to be proactive, start with targeted foot and ankle exercises. Do them consistently for at least two months before considering orthotics. Many children see meaningful improvement in this window.
Step 4: Consider orthotics if exercises alone are not enough.
If pain persists after a consistent exercise program, or if your child has rigid flat feet or an underlying condition, orthotics may be the appropriate next step. Use them alongside continued exercises, not instead of them.
Step 5: Reassess every 6 months.
Children's feet change quickly. An orthotic prescribed at age 5 may not be needed at age 7. Regular reassessment ensures your child isn't wearing insoles longer than necessary.

1. At what age do most children develop a visible arch?
a) 1 to 2 years old
b) 5 to 6 years old
c) 10 to 12 years old
d) Birth
Answer: b) 5 to 6 years old. Fat pads under the arch make younger children's feet appear flat even when the bone structure is developing normally.
2. What is the key difference between flexible and rigid flat feet?
a) Flexible flat feet cause pain; rigid flat feet do not
b) The arch appears on tiptoes with flexible flat feet but not with rigid
c) Only rigid flat feet occur in children
d) There is no difference
Answer: b) The arch appears on tiptoes with flexible flat feet but not with rigid. This distinction helps determine whether exercises, orthotics, or specialist evaluation is the right path.
3. What can orthotics NOT do for flat feet?
a) Reduce foot pain
b) Redistribute pressure across the foot
c) Permanently build or change the arch structure
d) Provide temporary support during sports
Answer: c) Permanently build or change the arch structure. Research shows orthotics manage symptoms but do not alter the natural development of the arch in children with flexible flat feet.
4. How long should you try exercises before considering orthotics?
a) 1 to 2 weeks
b) 8 to 12 weeks
c) 1 year
d) Exercises are never sufficient
Answer: b) 8 to 12 weeks. Most children see visible improvement in arch height and alignment within this window when exercises are done consistently.
5. Why might long-term orthotic use be a concern for some children?
a) Orthotics are too expensive
b) The foot muscles may weaken from lack of use
c) Orthotics cause blisters
d) Children outgrow them too fast
Answer: b) The foot muscles may weaken from lack of use. When insoles hold the arch in place, the muscles that should be doing that work get less activation, potentially increasing dependency on the orthotics.
Your Complete Footwear Reference
If you're weighing orthotics for your child, footwear choices matter just as much. My Ultimate Footwear Guide covers everything from shoe features to avoid, to the best options for children with flat feet, so you can make confident choices at the shoe store.
For families unsure whether their child's flat feet need professional attention, a personal diagnostic lets me evaluate your child's specific foot structure, movement patterns, and alignment so we can decide together whether exercises, footwear changes, or orthotics are the right path.
Most children with flat feet need stronger feet, not stiffer shoes. Start with movement, choose the right footwear, and let orthotics be the backup plan rather than the first step.
