My son loves these insoles. We got 2 pair and he used kne in his cleats for football and on in his reg tennis shoes for school. Highly recommend

Both my son's and daughter have reported more confort and less pain while using these. My oldest wears a size 16W and the largest available is what I bought. It insole fit well even tho it wasnt the exact size. Definitely recommend for heel pain and flat feet

Crystal

I gave it a 5 because so far the product is good, my son likes how they feel. The only problem I had was the delivery time. It took a long time to receive. I hope the can work on that matter.

Overpronation in kids is difficult

The goal is simple, to help kids get rid of foot, knee, and posture pain caused by flat feet and overpronation as fast as possible. Yet, the journey often feels difficult. You don’t know what’s causing the pain, what to use, or if anything will actually work. It’s frustrating, time-consuming, and expensive. But don’t worry, fixing overpronation doesn’t have to be complicated. Our philosophy is simple: support growing feet naturally with proper alignment and cushioning. That’s exactly what Footstr was built to do.

Our insoles are proven to relieve heel pain

1

Overpronation Control

Helps realign growing feet by correcting inward rolling, reducing pain in the heels, knees, and back.

1 in 4 kids have flat feet or overpronation

Your kid is not alone. Flat feet and overpronation are some of the most common issues in growing kids. If left untreated, they can lead to knee pain, poor posture, and even make them quit the sports they love. Footstr insoles were developed to prevent that, supporting growing feet with proper alignment and real pain relief.

The cause

The solution

The results

What’s the cause of overpronation in kids?

Overpronation and flat feet in kids often develop when the arches don’t provide enough support as they grow. Rapid growth, weak foot muscles, genetics, and unsupportive shoes can cause the arches to collapse and the ankles to roll inward, leading to pain and poor alignment.

The solution

To fix flat feet and overpronation, two things need to happen: proper support and long-term correction. Footstr insoles lift the arches to restore natural alignment, while advanced cushioning absorbs impact and relieves pressure, helping kids move comfortably and prevent future pain.

Clinically tested for overpronation and flat feet

In a clinical study, 40 kids and teens with flat feet and overpronation used Footstr insoles daily for 60 days. Testing showed a significant improvement in foot alignment and posture, along with reduced strain on knees and ankles.

How did this translate into real life results?

✅ 97% reported better foot alignment

✅ 93% said they could move and play without discomfort

✅ 90% of parents said Footstr™ worked better than anything else they had tried

"If we don't help you, we don't want your money!"

If our insoles don’t help your child feel real relief within 60 days of daily use, we don’t want your money. We know Footstr works, thousands of parents have seen amazing results, but we also know it might not be the perfect fit for everyone, and that’s okay.
