Ankle Sprain Rehab for a toe walker

So, some people walk on their toepads a lot of the time. I wouldn't say it's common but I am not the only one. When I am not wearing shoes I don't walk with flat feet. The main issue is tight hamstrings, which wasn't an issue untill I sprained my ankle.

I have been able to walk, somewhat, but I struggle to put weight on my heel, the stretch, and weight, hurts. I am trying to stretch and stuff, I am improving, but was wondering if anyone had insight on this?
