Similar to Xero Shoes, Earth Runners are minimalist barefoot running sandals inspired by renowned long distance runners, the Tarahumara Indians of Northwestern Mexico. The difference is that these have buckled straps instead of strings like you see in Xero Shoes so it's a little bit more convenient. And they're not just normal buckled straps - they're designed to keep you grounded to the earth via a copper plug on the bottom of the sandal. According to the book Earthing, there are some healing benefits when you're connected to the earth. Also unlike Xero Shoes, these sandals are custom molded and continue to mold themselves to your feet over time to ensure a great fit.
