Boost Boots give Sackboy an extra boost by pressing R1. Boost Boots are essentially a double-jump, for those out-of-reach platforms and Item Bubbles, because they only allow for one boost per jump. Boost Boots are recharged by landing on the ground or by jumping through a flashing yellow circle. Most levels throughout the game have hidden Item Bubbles that can only be reached with the Boost Boots equipped. We’ve got those all figured out in our walkthrough.
Use these to propel yourself skywards with a short burst of speed.
