The Jump Boots or AntiGrav Boots are a special power-up, that allow the player to jump a lot higher than normal. Additionally, if the boots are active, players take less falling damage and only at higher impact speeds than usual. The boots can be used for three high jumps and automatically wear off after landing from the third jump.
