These were probably quite expensive shoes, made of leather, very high quality, said one of the lead scientists, Gregory Areshian, of the Cotsen Institute of Archaeology at the University of California, Los Angeles.
The shoe was discovered by scientists excavating in a huge cave in Armenia, part of a treasure trove of artifacts they found that experts say provide unprecedented information about an important and sparsely documented era: the Chalcolithic period or copper age, when humans are believed to have invented the wheel, domesticated horses and produced other innovations.
