I love going barefoot, but my feet are old, and plantar fascitis kicks up in my heels after a week or so of padding around the house with no shoes on. I gave up wearing flip-flops 20 years ago, after I finally realized that the twinge in my knee was flip-flop induced.
I gave away all my fun shoes and now wear only sensible shoes with orthotics in every single pair. One podiatrist frowned at my insistent wearing of Birkenstocks.
