Hey @llfarms, *smiles.

Walking barefoot whilst in Nature is so very important because that is one way as to how we humans absorb the negative ions which the Earth radiates, and which are antioxidants for the human body.

If one cannot go barefoot, then wearing leather soled shoes is the next best thing. Wearing rubber soles, however, prevents the Earth's negative ions from being absorbed.
