What finally made sense was learning that kids do not need force they need guidance.
If you realign the ankle while gently supporting the arch the rest of the leg follows naturally.
When the foot is supported in the correct position it allows proper alignment while the muscles strengthen the right way.
That is when we realized the solution was not more exercises or expensive orthotics.
Those approaches either did not address the root cause or were simply too rigid for a growing foot.
What actually helped was giving his feet the right kind of support something that gently guided alignment without forcing it.
For us that solution was the Footstr insole which was recommended to us by Dr Blane.
They are designed specifically for kids feet with medial support to stop the ankle from rolling inward and flexible arch support that works with natural development helping the arch and foot muscles strengthen naturally not forcing them.
