Earth Runners® Earthing Adventure Sandals - Made in 。Great hiking/ water/ beach sandals. US men’s 15. Green, black, tan. Earth Runner’s have a copper rivet on the sole that supports grounding technology. 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. Check photo for signs of wear, very minimal. Thanks for looking! Send inquiries.
