Ancient shoe found
Washington - About 5 500 years ago someone in the mountains of Armenia put his best foot forward in what is now the oldest leather shoe ever found.
It will never be confused with a modern shoe, but the well-preserved footwear was made of a single piece of leather, laced up the front and back, researchers reported on Wednesday in PLoS One, a journal of the Public Library of Science.
Worn and shaped by the wearer's right foot, the shoe was found in a cave along with other evidence of human occupation. The shoe had been stuffed with grass, which dated to the same time as the leather of the shoe - between 5 637 and 5 387 years ago.
"This is great luck," enthused archaeologist Ron Pinhasi of University College Cork in Cork, Ireland, who led the research team.
"We normally only find broken pots, but we have very little information about the day-to-day activity" of these ancient people. "What did they eat? What did they do? What did they wear? This is a chance to see this... it gives us a real glimpse into society," he said in a telephone interview.
Previously the oldest leather shoe discovered in Europe or Asia was on the famous Otzi, the "Iceman" found frozen in the Alps a few years ago and now preserved in Italy. Otzi has been dated to 5 375 and 5 128 years ago, a few hundred years more recent than the Armenian shoe.
Otzi's shoes were made of deer and bear leather held together by a leather strap. The Armenian shoe appears to be made of cowhide, Pinhasi said. Older sandals have been found in a cave in the state of Missouri, but those were made of fibre rather than leather.
The shoe found in what is now Armenia was found in a pit, along with a broken pot and some wild goat horns.
But Pinhasi does not think it was thrown away. There was discarded material that had been tossed outside the cave, while this pit was inside in the living area. And while the shoe had been worn, it wasn't worn out.
It's not clear if the grass that filled the shoe was intended as a lining or insulation, or to maintain the shape of the shoe when it was stored, according to the researchers.
The Armenian shoe was small by current standards - European size 37 or US women's size 7 - but might have fit a man of that era, according to Pinhasi.
He described the shoe as a single piece of leather cut to fit the foot. The back of the shoe was closed by a lace passing through four sets of eyelets. In the front, 15 pairs of eyelets were used to lace from toe to top.
There was no reinforcement in the sole, just the one layer of soft leather. "I don't know how long it would last in rocky terrain," Pinhasi said.
He noted that the shoe is similar to a type of footwear common in the Aran Islands, west of Ireland, up until the 1950s. The Irish version, known as "pampooties" reportedly didn't last long, he said.
"In fact, enormous similarities exist between the manufacturing technique and style of this (Armenian) shoe and those found across Europe at later periods, suggesting that this type of shoe was worn for thousands of years across a large and environmentally diverse region," Pinhasi said.
While the Armenian shoe was soft when unearthed, the leather has begun to harden now that it is exposed to air, Pinhasi said.
