"Fuzzy logic tries to get machines to think like people do, with inexact fuzzy terms."
- Bart Kosko

Magneslippers  
  Shoes that adhere to metal space ship floors, useful in null gravity situations.  

Gingerly Docchi tried out the magneslippers; he was clumsy, but no longer helpless in the gravityless ship...

Anti led the way because Docchi couldn't get around her. Determinedly he shuffled along. There was a trick to magneslippers that he had nearly forgotten. Slowly it was coming back to him—shuffle instead of striding...

Docchi went as fast as the magneslippers would allow, which wasn't very fast.

From Accidental Flight, by W.F. Wallace.
Published by Galaxy in 1952

Robots don't need them:

Unlike man, it didn't need magneslippers. It had magnetic metal feet which could move fast, and did.

Compare to magnetic shoes from The Dual World (1938), by Arthur K. Barnes.
