Details from Earth Runners: - Our thinnest and quickest drying adventure sandal, the Primal features a 7.5mm Walkbase® sole, for unmatched ground feel. - Our sandals are designed to keep you grounded via Grounded Conductive Laces™. When worn on bare earth, Earth Runners give you an effective connection with the ground, through a copper lace plug on the outsole. Electron transfer between your body and the earth is facilitated through the stainless-steel lined lace circuit. This process grounds the body via intimate connection of lace and foot–similar to that of being barefoot. I generally use minimal packaging to ship, often in reused mailers, while still properly securing the package for safe transit. Feel free to contact me if you have any questions! Thanks for looking!
