Feel It In Your Sole

I don't remember which sermon inspired this one but I believe it was a throwaway comment about cobbling something together or something soul-related. My mind tends to go on tangents which is why it's helpful that our pastor gives out sermon outlines to help me (and probably other people too) focus. I'm now thinking it was something more soul-related. But of course I went on a tangent. Not a cosine. Why don't we go on more cosines.

M: How do you know that your shoes are wearing out?
B: I can feel it in my sole.
