The Ur-Sneaker: 5500-Year-Old Shoe Found in Armenian Cave

Three jaw-less heads and one really old shoe. These aren't the clues in a Law and Order episode; they're findings from a limestone cave in Armenia. As described in a paper published yesterday in PLoS ONE, archaeologists believe they have found the world's oldest leather shoe: it's 5,500 years old. "It's pretty weird," said lead author Ron Pinhasi to CNN regarding the disembodied heads and the placement of the well-preserved shoe. The ancient sneaker was stuffed with grass, though archaeologists can't say whether the grass was intended as insulation or whether it helped maintain the shoe's shape.
