Experience this unique concept in men’s and women’s footwear through your sole— a zero-drop sole made from porous water buffalo leather that’s ethically-sourced. This material is extra conductive as it absorbs the earth's moisture and your perspiration. Each pair has a copper rivet hammered through the sole that touches your KD1 pressure point under your foot to directly contact the earth, making you fully conductive. Your feet mold into the leather over time creating an amazing level of comfort that brings you back to how your body was designed to feel.
