Each o’ merla features a 100% copper rivet embedded into the handmade leather shoe sole, creating a direct connection between your body and the Earth, which

allows you to benefit from the Earth's natural electrical charge. Copper allows electrons to move freely through the metal into the soles of

your feet, creating a grounding effect in the body. This uninterrupted electron flow has been shown to improve circulation, reduce

inflammation, lower stress levels, and enhance sleep quality.
