So I was looking at Voskhod 1 stuff..

[Randazzo]

Wikipedia has this image, titled only "Voskhod crew after landing" :

I know the crew didn't wear spacesuits for the flight, but what do you think the chances are that Konstantin (guy on the right) went to space wearing loafers?

Talk about space lounge.

[PlonioFludrasco]

Just my 2 cents: Probably they changed their shoes as soon as they left the capsule.

[Cydonian Monk]

Somebody that was shot in the face and lived, went on the be a prominent engineer under Korolev, all while NOT being a card-carrying member of the Communist Party? Oh, and also lead the Soviet's space station design group? I'd say Konstantin Feoktistov was probably "BadS=Y" enough to wear loafers into space.

(Yes, he probably changed shoes after landing. Still....)

[Deutherius]

He's an engineer. He obviously chose shoes without shoelaces to reduce payload mass and allow greater vehicle capabilities
