Glute stretch? Good stuff!
In general I'd encourage you to explore stuff on your own and freestyle on things like stretching and soft tissue work (rolling etc.), but in terms of corrective exercises I have in mind a particular order to go with.
It makes things massively easier for me that you're interested in this stuff
I'm going to give you the weekend to work on your foot and then have something for you to work on for monday. Fixing your feet is literally the foundation to sorting everything else.
How do you feel about progressing at some stage to doing some sprinting? A top down way of looking at this is that if you can sprint, your body is working pretty well. It's also incredibly good for you.
