Good article with research background on the many health benefits of walking barefoot on certain surfaces or ‘grounding’ with some types of shoes or mats. My personal favorite is walking on the beach, but Idon’t get the opportunity to do that much these days. Here in the Natural State, walking on grass (no pesticides? ) or ground would work, except for all the rocks. As the article states:
“We all spend most of our time walking on the earth wearing shoes with rubber or plastic soles. These materials are insulators, used to insulate electrical wires. They also disconnect you from the Earth’s electron flow, which we are supposed to (naturally) be connected to. If you wear leather-soled shoes (or vegan leather!) or walk barefoot on sand, grass, soil, concrete, or ceramic tile, you will be grounded. If you walk on asphalt, wood, rubber, plastic, vinyl, tar, or tarmac you will not be grounded.”
