Grind Boots are a recurring gadget in the Ratchet & Clank series, which have appeared in most entries. They are boots that allow Ratchet to grind and move on grindrails, poles, train lines, telephone poles, among other specific locations. Ratchet can hop between adjacent rails. They feature a red design developed by Gadgetron, though Vox Industries have developed their own.
Grind boots are used to traverse grind rails found in various locations, such as construction beams, telephone poles and train lines. These rails often contain obstacles which Ratchet must jump across. Ratchet can use the OmniWrench to destroy obstacles and enemies along the path.
In All 4 One, larger grind tubes are used in place of grind rails, to allow four players to grind at once. These are otherwise functionally identical.
