Charles Blondin's Unitard

Origin
Charles Blondin was a French tightrope walker & acrobat known for his combination of grace and originality while on the wire. His first major break was crossing the Niagara Gorge, which launched him to stardom. He repeated this with many variations, from walking blindfolded or on stilts to carrying his boss upon his back over the gap.

Effects
Allows the wearer to defy gravity by literally walking on air. The only catch is that it only works so long as they walk in a straight line. If they stray to either side, they drop straight down.
