I received my pair of Pluggz Flip Flops the other day. I wasn't home when the mailman showed up so I thought that I would have to wait to pick them up. When I went out to the lobby to check the mail I saw a package sitting in the flower pot in the corner. Guess the mailman knew these shoes were all about reconnecting with the earth.
The Flip Flops have a plug in the center that is designed to allow energy to transfer from the ground into your body. I have not read much on the theory of grounding but I will before I finish my review.
