Insoles with instep support (10 year old) with dropped arch

[Gerbi1]

Hello, can anyone recommend a decent insole for my sporty 10 year old with a slightly dropped arch on his right foot. He’s complaining of pain in his tendon and heel after running

Thanks

He should be entitled to NHS Podiatry treatment to fully assess his problem. It might not be completely sports related. Get it checked out. You can sometimes self refer.

Thanks I’ll talk to the gp and find out how to do that
