"I feel like I've been very fortunate in that I've stuck like a burr to the dog-leg of the next generation of nerdism. I've been carried into the XXIth century on Bill Gates' pants-cuff."
- William Gibson

Magnetic Sandals  
  Special footgear to walk in zero-gee spacecraft.  

Jim Davis had come into view... He bounced by, walking on magnetic sandals, looking like a comedian as he bobbed about the magnetic plates. "Hi, group," he called as he went by.
From The Warriors, by Larry Niven.
Published by Worlds of If in 1966

Compare magnetic sandals to magnetic-soled shoes from Murray Leinster's 1953 novel Space Tug and the magnetized boots from Manly Wade Wellman's 1941 story Lost Rocket. A slightly different technology is used in the nifty grip shoes from 2001: A Space Odyssey.
