She was not strong. She was valiant. Radiant. Brave and broken. The beauty she discovered in the aftermath was unparalleled to anything she had known before, because it had come at such a cost.

I don't think having a bad/old pair of shoe will cause all those problems so quickly. If they have lost their supportive qualities, you will feel the effects over several days in a row of wearing them. The only way to see if it's time to toss them out is to alternate your runs with and without them and see how you feel afterwards.
