Barefoot running coach takes tips from native tribe

Several years ago, the book Born to Run helped to push the unusual practice of barefoot running into the mainstream across the world.

Barefoot running is running with little to no foot protection, which proponents say is healthier for the foot.

The work chronicled the adventures of journalist Christopher McDougall and his coach, Eric Orton. The men ran alongside the Tarahumara Indian tribe - Mexicans who have been known to strap old tire scraps to their feet and run more than 100 miles (161km) on little food.

Though a recent study suggests barefoot running could lead to leg injuries in some runners, advocates say human feet are naturally designed to run bare on the ground and not in cushioned shoes.

The BBC's Matt Danzico sat down with Mr Orton at his home in Jackson, Wyoming, to learn about more secrets he obtained from the Tarahumara tribe.

Mr Orton has written about these experiences and shares new running tips in his book, The Cool Impossible.
