The Hi-Jump Boots, formerly known as High Jump Boots, allow Samus to increase the height of her jump. It was first featured in Metroid and has been in every 2D Metroid game since. The Hi-Jump Boots also allow Samus to jump in Morph Ball mode in Metroid Fusion and Metroid: Zero Mission, while in Metroid II: Return of Samus and Super Metroid, a separate upgrade is required.
