Was just reading Mike Massimino's memoir Spaceman and came across this fascinating line:
Another time a spacewalker - and this is a true story - accidentally put his right boot on his left foot and put his left boot on his right foot. Once he got outside, he couldn't fit in a foot restraint.
Some searching turned up a reference to (presumably) the same incident in Clay Anderson's book It's a Question of Space.
Neither reference gives any more information.
Can anyone provide more details?
