Have you ever wondered why it feels so good to walk barefoot on the ground? ??It's because we're all standing on a powerful, natural energy source - the Earth and when we walk barefoot we absorb this energy in the form of "electrons". This enables us to GET GROUNDED. Grounding, also called Earthing, is amazing for our bodies and makes us feel great. Every pair of Ballet Flats contains a proprietary carbon and rubber black plug embedded into the soles which allows for the free flow of electrons from the Earth into our bodies, enabling us to get grounded when we walk on grass, sand, soil - even concrete city sidewalks. Pluggz Ballet Flats are made of supple, full grain leather with skid resistant rubber soles and moisture wicking, anti-microbial lining. Contoured arches and padded heels make them extremely comfortable and provide support, with a custom trampoline heel for stability and a light step. Available in full and half sizes: 6 - 10.5.
