In the space shuttle andOn the International Space Station, why don't astronauts wear a pair of shoes with magnetic soles?

Walking in magnet shoes is just an innocent way for kids watching science fiction movies to come up with, and it's not practical at all. Flying around is a very convenient way to move in a space capsule. As for the equipment being affected, not so much. Hundreds of millions of dollars of sophisticated instruments are not affected by this, and many of them generate magnetic fields themselves. The practical application is not to write science fiction fairy tales. Because there is no gravity, astronauts have to use special tableware to eat in space to prevent food from floating away accidentally. The space station and other spacious spaceflightInside, there is usually a special dining table.

In the space shuttle, astronauts usually sleep in the command chair, a chair in the flight room, or on a bunk. A shuttle has only four beds, which means that if there are five or more astronauts, the extra crew must sleep in sleeping bags, chained to the wall or chairs.
