Both Nurse's and Waitress's are experts in foot pain.
If they find something that helps You better listen...
You don't want to be so open-minded that your brain falls out.
There might be a very simple, physically plausible mechanism: walking barefoot uses the foot muscles differently, and could relieve cramps and hot-spots. No need to posit unmeasurable static charge build-up. (If it was that, dissipating the charge by grabbing on to a grounded metal pipe should work just as well, or better.)
