Magnetic 'MoonWalker' Shoes Help You Defy Gravity

The shoe, named "20:16 MoonWalker," relies on N45 neodymium magnets, which are among the most powerful permanent magnets known. As permanent magnets, they create their own force field, without an external current, and work like refrigerator magnets. "There are different levels of magnets, like N40, 42 and 45," said Patrick Jreijiri, a mechanical engineer and designer for the 20:16 MoonWalker.
