Interesting outlook. I have always preferred sandals, though I’ve worn work boots most of my life out of necessity. Recently I discovered Crocs and I think they are the best thing I’ve ever worn. They are as close to being barefoot as I can get. I “wash” my feet with soil daily. I never wash them in the classical sense, fun fact, within five minutes of skin contact with soil, the microbiome on your skin begins to change in ways specific to the soil. Touching earth is critical to the balance of microbial cultures, eating it too, though I am not yet one of those people. 😁
