Studying Oscar Pistorius: Does The ‘Blade Runner’ Have An Advantage? [Video]

The technology that makes walking possible for amputees is also making running possible at the Olympics. On Saturday in London, South African Oscar Pistorius will run on artificial limbs in the 400-meter sprint. Pistorius is a double amputee who runs world-class times on his carbon-fiber legs.

At last month’s Prefontaine Track and Field Classic in Eugene, Ore., Pistorius ran in the inside lane of the 400-meter race. He leaned forward on his knees and fingers, and slipped his feet into the starting blocks — well, they’re not actually feet.

Instead, Pistorius slipped the flat and spiked bottoms of his curved carbon-fiber legs into the blocks. In the other lanes, all the blocks were filled with track shoes, tied tight around flesh, blood and bones.
