Jet Boots

The jet boots are a new technology used by Zero Suit Samus in Super Smash Bros. for Nintendo 3DS and Wii U. Like the Plasma Whip, they are an invention of the Super Smash Bros. series and have not appeared in a Metroid series game. They come with matching bracelets and are a new recovery (replacing the Plasma Wire) and attack move. In the recovery, Samus seems to kick up in midair and she flies up with the boots. Masahiro Sakurai, in the April 2014 Nintendo Direct explains that these boots were created out of a viewed necessity to "toughen her up", as Zero Suit Samus was not very strong in Super Smash Bros. Brawl. Indeed, they augment her returning kick moves and seem to make them more powerful. They seem to be an attachment and are a new modification to the otherwise identical Zero Suit from Metroid: Other M, which controversially featured Samus in larger, clunky heels.
