    "summary": "Hair-on calfskin upper, cow leather lining, a water buffalo leather sole and a copper earthing plug. That's the whole materials list, and the maker says the shoes have no synthetic rubber-plastic outsole, which is a good start. The open question is the leather: finished leather often carries an acrylic or polyurethane topcoat, and undyed isn't the same as uncoated. Nobody states the finish on the upper, the lining or the sole. The insole, the stitching thread and the glue aren't named either, and all of them sit against your foot.",
