Sunita Williams to develop 'baby feet' after returning to Earth

NASA astronauts Sunita Williams and Butch Wilmore will develop 'baby feet' after returning to Earth after a prolonged 9-month stay in space, ex-NASA astronaut Leroy Chiao said. "You basically lose the thick part of the skin on your feet. You kind of have baby feet when you come back," Chiao said. "The foot calluses come back very quickly," he added.
