I run and had PF a few years ago. I saw one of the best podiatrists, per Run Washington, as he was recommended by a friend who runs. The podiatrist is a runner and runs Boston every year so I trust that he understands both running and podiatry.
For PF, he had me increase my strength and core work. If your core is weak, your gait is affected.
Planks, one legged balance exercises, and bridges. Also something called "Toe Yoga". Here's a link for Toe Yoga:

I do not have PF any more.
For your hips, you should do clam shells and rose wall slides. (Google them if you don't know them.) Side planks, too.
