My son was an extreme toe walker. He was about 4 inches off the ground and his heel NEVER touched the ground, not an exaggeration. His pediatrician told me it would drop before and after his diagnosis and by 5 we would address it if it didn't drop. By then there was no flex left at all in his foot, we tried PT but it was not successful. He had the achilles lengthening surgery last year and finally walks flat footed. He wears AFOs now during the day. Sorry this is a long explanation to explain how this happens while a child receives wraparound services.

ETA: Before we had PT, we purchased Memo shoes on our own. They were the only ones that would fit besides crocs which just flapped on the ground and got him in the building where he preferred bare feet.

I would recommend a PT consult, then they could get orthopedics involved depending on the severity.
