Flat Feet in Toddlers and Kids: What's Normal, and Which Shoes Help

Quick answer
Flat feet (low or no arch) are normal and expected in babies and young children. According to the American Academy of Pediatrics and the American Academy of Orthopaedic Surgeons, nearly all young kids look flat-footed, and arches usually develop on their own, commonly by around age six. For painless "flexible" flat feet, pediatric guidance says kids don't need shoe inserts or arch supports. Foot-shaped, flexible shoes help simply by letting the foot move. See a doctor if the feet are painful, stiff, or flat on one side only.

First, take a breath

If your toddler's feet look completely flat when they stand, you're seeing something almost every young child has. Babies are often born with flat feet, and it can last well into childhood because little bones and joints are so flexible that the foot flattens when they stand. A small pad of baby fat also fills in where the arch will eventually be. It looks like a problem, but in the vast majority of kids it's just a normal stage of growing.

If you've been searching "arch support shoes for kids" or "how to fix flat feet," here's what the pediatric research actually says, in plain language.

Full disclosure: we make kids' shoes, so we have a stake in this. That's why we lean on what pediatric groups say rather than on our own opinion.

What's actually going on with your child's arches

The arch is built by muscles, ligaments, and bones that are still developing through early childhood. As a child grows and walks, the soft tissues along the bottom of the foot gradually tighten and shape the arch. It's completely normal for it not to be visible yet.

Flexible flat feet (the common, harmless kind)

Most childhood flat feet are "flexible." That means an arch appears when the child is sitting, on tiptoes, or with the foot dangling, and then flattens out when they stand and put weight on it. This kind is painless, doesn't get in the way of running and playing, and is simply part of normal development.

Rigid flat feet (rare, worth a look)

Much less common is a "rigid" flat foot, where the arch stays flat even when the child is on tiptoes or not bearing weight, and the foot may feel stiff or sometimes sore. This is the type worth having a doctor evaluate, because it can occasionally point to something that benefits from care. It's the exception, not the rule.

Flexible flat feet Rigid flat feet
Arch appears on tiptoes? Yes No
Painful? Usually not Sometimes
How common in kids? Very common Rare
What it usually needs Nothing A doctor's evaluation

Will my child grow out of flat feet?

Usually, yes. As the foot muscles strengthen and the bones mature, the arch tends to develop on its own. Children with flexible flat feet often don't begin to show an arch until age five or older, and flat feet commonly settle by around age six. Only about one or two children in ten carry flat feet into adulthood, and many of them never have any problem from it. For painless flexible flat feet, "growing into an arch" is the typical path, and it happens without special equipment.

Do kids need arch support shoes or insoles?

This is the question most parents are really asking. For painless, flexible flat feet, pediatric and orthopaedic sources are clear: children don't need shoe inserts or arch supports, and "supportive" stiff shoes don't build the arch. The arch forms through the foot doing its own work, not through being propped up from below.

In our view, a lot of "arch support" marketing speaks to a worry that, for most kids, the evidence doesn't support. We're not saying those products are harmful. We're pointing you to what the pediatric guidance says, which is that for a typical painless flat foot, inserts aren't necessary and don't change the outcome.

The exception is the child who has pain or a rigid foot. If a doctor evaluates your child and recommends a specific support or insole, follow that advice over any general article, including this one.

What pediatric sources recommend instead

If support isn't the answer, what does help a developing foot? Two simple things, neither of which is a product claim:

Barefoot time. Letting little feet go bare on safe surfaces lets the small foot muscles grip and work, which is part of how strength and the arch develop. Even 30 to 60 minutes a day of safe barefoot play counts.

Shoes that don't get in the way. When shoes are needed, the goal is not to restrict the foot. That means flexible (bends easily), foot-shaped with a wide toe box (toes can spread), flat from heel to toe (zero-drop), and light. A shoe like this doesn't prop up or correct anything; it just lets the foot move and the muscles do their job.

When you should see a doctor

Flat feet are usually nothing to treat, but check in with your pediatrician if you notice:

  • Foot, ankle, or leg pain, or your child asking to be carried more than expected
  • A foot that's stiff or flat even on tiptoes (a possible rigid flat foot)
  • Flatness on one side only
  • A foot that seems to be getting worse rather than better
  • Trouble keeping up, frequent tripping, or unusual shoe wear

These don't mean something is necessarily wrong; they're simply signs worth a professional look.

So what shoes should a flat-footed child wear?

The short answer: a regular, well-fitting shoe that lets the foot move naturally. You don't need an arch-support or "motion-control" model. Look for a flexible sole, a wide toe box, a flat (zero-drop) profile, and a secure fit.

Arch-support / "supportive" shoes Stiff conventional shoes Foot-shaped (barefoot) shoes
Builds the arch? No evidence No No, but lets it develop naturally
Toe box Often narrow Tapered Wide, foot-shaped
Sole Rigid, built-up arch Stiff Flexible, zero-drop
Lets foot muscles work Limited Limited Yes
Typical cost $$$ $$ $$

FAQ

Are flat feet normal in toddlers?
Yes. Nearly all babies and toddlers look flat-footed because the arch hasn't formed yet and a fat pad fills the space where it will be. In the large majority of children this is a normal stage, not a problem, and the arch develops on its own with time.

At what age do children develop arches?
Children with flexible flat feet often don't begin to show an arch until age five or older, and flat feet commonly settle by around age six. Some children form arches a little later, and only about one or two in ten keep flat feet into adulthood, usually with no problem.

Do kids need arch support for flat feet?
For painless, flexible flat feet, pediatric and orthopaedic sources say no. Children don't need shoe inserts or arch supports, and they don't help the arch develop. Support may be considered only when a child has pain or a rigid foot, as guided by a doctor.

Are barefoot shoes good for kids with flat feet?
Foot-shaped, flexible shoes let the foot move and the muscles work, which is what a developing foot benefits from. They aren't a treatment for flat feet, but they don't restrict the foot the way stiff, arch-support shoes can. Follow your doctor's advice if your child has a diagnosed condition.

When should I worry about my child's flat feet?
It's worth a doctor's look if there's pain, a stiff or rigid foot, flatness on only one side, worsening over time, or trouble keeping up. Otherwise, painless flat feet in a young child are usually just a normal stage.

Can flat feet be fixed with special shoes?
For typical painless flat feet, special shoes don't build an arch and aren't needed; the arch develops through normal growth and movement. A normal flexible, foot-shaped shoe is generally all that's required.

What's the best shoe feature for a flat-footed child?
Flexibility. A sole that bends easily, with a wide toe box, lets the foot move and the muscles strengthen, which is what supports natural development at this age, rather than a built-up arch.
