While the Doctor was delighted with his Ganger, Amy wasn't so trusting of him. To reassure her, the Doctors pointed out that they could be told apart by looking at their shoes, as the original Eleventh Doctor had his burned off in acid after the flesh had scanned him to create his counterpart. At some undisclosed point in time, the Doctor and his Ganger switched shoes and pretended to be each other, to prove to Amy that the Gangers were people in their own right. At one point, this backfired as Amy accidentally revealed information about the Doctor's death at Lake Silencio to the real Eleventh Doctor, rather than the intended flesh duplicate.
