In Dayni Moon go to Clank's Challenge and beat the last Gadgebot Survival and Gadgebot Toss to win Mega Bomb Boots and Mega Bomb Gloves
There are no charge boots in crack in time, so I guess so, but the hover boots are in my opinion better and beat the charge boots by a long shot.
Slingshot, Trespaser, Hydro Displacor, Persuador, O2 Mask, Pilot's Helmet, Hele-pack, Thrusters-pack, Hydro-pack, Gravity Boots, Grind Boots, Taunter, Holo-guise, Gadgetron PDA, Infobots. And I think that's it.

Go to planet Orxon. Go to the area right next to the ship landing pad where you can play as Clank. Go through the area as Clank, and when you get to a large circular room with several halls leading off of it, go to the doorway with the boots in it.
Go to planet Joba (The Megacorp Games), and do the first arena battle there. If you win you get gravity boots.
