👣 Frequently Asked Questions About Children’s Flat Feet
Parents often contact us with similar concerns when they notice their child's feet collapsing or when their child complains of foot or leg discomfort.
Below are some of the most common questions we hear.
1️⃣ “Flat feet run in our family. Is my child condition inherited?”
Flat feet themselves are not directly inherited.
However, joint hypermobility (extra flexible joints) can run in families. When a child's joints are more flexible than usual, their arches may collapse more easily when standing or walking.
Children with higher joint flexibility may benefit from activities that develop muscle control and balance, such as playing barefoot on grass or sand.
However, if the arches collapse significantly during walking or your child complains of foot fatigue or pain, it may be worth assessing how the feet are handling body weight.
2️⃣ “Neither side of our family has flat feet. Why does my child have them?”
There are several possible reasons:
-
Inherited joint flexibility from a grandparent
-
Limited exposure to natural ground surfaces during early walking
-
Tight calves or weak foot muscles affecting foot mechanics
-
Footwear that does not provide adequate stability for developing feet
When these factors combine, the arch may collapse more easily during movement.
The key issue is often how the foot controls load during walking, rather than the appearance of the arch itself.
3️⃣ “My husband has flat feet and lives normally. Should I still worry about my child?”
Many adults with flat feet live without major problems.
However, we also see adults in their 30s or 40s who begin developing knee, ankle, or back pain after years of compensating for poor foot mechanics.
When the foot collapses repeatedly during walking, the body may gradually adapt in ways that increase stress on other joints.
The important question is not simply whether flat feet exist.
It is whether the flat feet are flexible and still correctable while the child is growing.
4️⃣ “My child wears Crocs a lot. Could that cause flat feet?”
Yes, it could contribute.
Crocs are soft and unstable, so they don’t provide a firm base for proper walking.
When the foot steps on something soft, it tends to tilt inward especially in kids with flexible ankles.
This can lead to overpronation (foot rolling in too much) and flattened arches over time.
Crocs are fine for short, casual use but not ideal as everyday footwear for growing children.
5️⃣ “If Crocs aren’t suitable, what kind of shoes should my child wear?”
Choose shoes that:
-
Have laces you can tighten
-
Have a firm heel counter (the back of the shoe should feel solid)
-
Offer a stable base, not too soft or bendy
For sandals, look for ones with three adjustable straps at the toes, around the ankle, and behind the heel.
These designs hold the feet firmly and encourage proper walking mechanics.
6️⃣ “My child has been wearing insoles for years, but nothing has changed. Why?”
Insoles give temporary support, not correction, just like wearing glasses helps you see clearly only while they’re on.
Once the insole is removed, the arch flattens again because the muscles haven’t learned to hold the arch themselves.
In Western countries, people wear shoes all day, even indoors, so insole therapy works better.
But in Asian homes, where children go barefoot most of the time, insoles alone rarely make a difference.
For growing children, improving how the foot controls load during walking and running may be more important than simply holding the arch up.
7️⃣ “My child’s feet became flat after the MCO (pandemic). Why?”
During the MCO, many children stayed indoors and stopped doing physical activities.
Their bones continued to grow, but their muscles didn’t, leading to muscle tightness, especially in the calves and hamstrings.
As a result, their feet started to roll inward (overpronate) to compensate, causing flattened arches and poor posture after the growth spurt.
8️⃣ “My child is 17. Is it too late to fix flat feet?”
Not necessarily.
If the ankle joints are still flexible, non-surgical correction is still possible.
Most joints start to stiffen around age 11, but some remain flexible longer.
With structured gait retraining (First Ray Control Framework), many teens can still improve their arches and posture significantly.
9️⃣ “My child is now an adult. Can it still be corrected?”
It depends on their joint flexibility.
We’ve seen adults, even up to 37 years old, successfully restore their arches with proper gait retraining because their ankles remained flexible.
A quick physical assessment can help us determine whether your feet still have the potential to improve.
Final Thoughts for Parents
Consider evaluation if your child:
-
complaints of foot or heel pain
-
gets tired quickly during walking or sports
-
has ankles collapsing inward when standing
-
frequently trips or shows poor balance
An assessment can determine whether the flat feet are flexible and suitable for correction during growth.
Flat feet are common in children, but persistent symptoms such as pain, fatigue or unstable walking may indicate that the foot is not controlling body weight efficiently.
The earlier this is assessed, the easier it is to understand whether correction is possible.
