Has your child been complaining about leg pain lately? Are they refusing to participate in sports? Most kids with leg pain get written off as having “growing pains.” In some cases, however, the pain traces back to a real underlying condition like flat feet or weak ankles. As a shoe fitter with years of experience, I’ve seen firsthand how the right shoes and orthotics can make a real difference. Since the whole body is connected, a foot condition can create ripple effects well beyond the foot itself. This is exactly why early intervention matters.

The Most Common Culprit: Flat Feet

Flat feet can cause an imbalance that leads to leg pain. Because the body is one connected system, an imbalance in the foot doesn’t stay contained there. Instead, it affects the ankle, knee, hip, and sometimes even the lower back.

The Role of Orthotics

Orthotics are specially designed insoles that support the feet. They’re particularly useful for kids experiencing discomfort from structural foot problems. By helping align the feet properly, they reduce stress traveling up through the legs and improve overall posture.

Before and After

In the before image, you can see a child with flat feet and heel eversion standing barefoot.
In the after image, the same child is standing with the orthotics I recommend. Notice how the feet are straighter. The deep heel cup and medial and lateral flanges are properly aligning the feet.

Another Common Cause: Intoeing (Pigeon Toe)

Intoeing — sometimes called pigeon toe — is a condition where the toes point inward rather than straight ahead. It’s common in young kids and usually resolves on its own as they grow. However, in some cases it contributes to leg pain and needs intervention. Orthotics can help support and gradually correct the underlying positioning.

Here’s a before image of a child with intoeing standing barefoot. Do you notice how the feet are angled inward?
Here’s the after image of the same child, now wearing supportive shoes and orthotics. Do you notice the improvement in foot posture?

Something as simple as the right orthotic and shoe combination can make a real difference in a child’s foot posture and walking gait.

What Makes This Orthotic Effective

Deep heel cups. These help maintain correct foot positioning, which is essential for proper alignment. The orthotic I recommend below has a deep heel cup that controls the alignment of both the heel and lower leg.

Medial and lateral flanges. These provide additional side support, controlling excessive foot motion and improving overall stability.

Over the years, I’ve fitted just about every type of orthotic — full-length, quarter-length, AFOs, and SMOs. LittleSTEPS orthotics have consistently been the most effective at reducing or fully eliminating foot and leg pain in the kids I’ve worked with.

Best Orthotic for Kids with Leg Pain: LittleSteps

LittleSteps offers real arch and heel support while being less intrusive than more rigid options. This design supports your child’s feet without getting in the way of natural foot and leg muscle development. As a result, those muscles keep growing stronger and more aligned on their own.

  • No need to remove the shoe’s original insole
  • 3/4-length design fits most shoe styles
  • Use this sizing chart based on your child’s shoe size
  • Ideal for leg pain linked to flat feet, weak ankles, or intoeing

Orthotics don’t make a child’s muscles “lazy” or weaker — they provide structural support while the foot and leg muscles keep developing naturally. In fact, think of an orthotic as a guide for that growth, not a replacement for it.

Many therapists get frustrated when a well-chosen orthotic ends up inside the wrong shoe. This is because a poor-fitting shoe makes the whole condition harder to manage. The orthotic needs to sit inside a properly supportive shoe for your child to get its full benefit.

What Shoes Work Best with This Orthotic?

I’ve put together a full list of deep, supportive shoes built specifically for kids who wear orthotics. These shoes feature sturdy soles, extra depth, and features designed to work seamlessly with an insert like this one.

Keep the Orthotic in Place

A properly laced shoe keeps the orthotic from shifting during activity. This lacing technique is built specifically for kids wearing an orthotic inside their shoes.

Has Your Child Been Diagnosed with “Growing Pains”?

Before assuming your child’s leg pain is just growing pains, it’s worth checking with a medical professional. There’s actually no solid evidence directly linking “growing pains” to growth spurts — it’s a common label, but not a well-established mechanism. In addition, it’s worth noting that growing pains are almost always felt in both legs. Pain isolated to one leg is more likely a sign of something else worth investigating.

Contact Me for a Specific Recommendation

Every child’s leg pain has a different underlying cause and severity. Reach out directly and I can help you figure out whether an orthotic, a shoe change, or both make sense for your child’s specific situation.

Final Thoughts

Leg pain in kids is sometimes genuinely just growing pains from running, jumping, and climbing — but don’t default to that assumption. Joint or leg pain can sometimes signal a real underlying condition. Therefore, have your child evaluated by a medical professional to rule out a specific foot condition affecting the legs. If flat feet or weak ankles turn out to be the cause, it’s worth being proactive — every structure above the foot depends on what’s happening at the foot itself.

Orthotics can be genuinely life-changing, but they’re part of a broader approach to managing leg pain, not a stand-alone fix. A comprehensive assessment from a healthcare professional, alongside the right footwear, gives you the best chance at a real, lasting improvement.

Frequently Asked Questions

How can I tell if it’s really growing pains or something more serious?

Growing pains are almost always felt in both legs, often at night, and aren’t tied to a specific spot. Pain concentrated in one leg, tied to a specific area (like the heel or arch), or that affects how your child walks is more likely linked to an actual foot condition worth investigating.

How soon should I expect to see improvement?

It varies by child, but many parents notice a reduction in complaints of leg pain within a few weeks of consistent use, especially when paired with properly fitted, supportive shoes.

My child’s leg pain is only in one leg — should I be concerned?

Yes, it’s worth having this evaluated. Growing pains are typically bilateral (both legs), so pain isolated to one leg is more likely tied to a specific, addressable cause rather than general growth-related discomfort.
