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.
Ratchet & Clank
The Grind Boots make their debut, purchased on Blarg Tactical Research Station in Nebula G34 from the engineer Fred. They cost 2,000 bolts, the price Fred sold them for including the employee discount.
The Grind Boots return, but this time feature a new, metallic design manufactured by Vox Industries. They are available immediately. Ratchet can only use the Dual Vipers on the grind rail, though.
In other entries, the Grind Boots are immediately available for Ratchet for no price, and use their Gadgetron design.
