I searched everywhere on the forums, and i'm surprised this hasn't been posted here before.
1) Get a pair of boots that has a rocket boot effect
Goblin Rocket Boots
Gnomish Rocket Boots
Rocket Boots Xtreme
Rocket Bootx Xtreme Lite
2) Enchant them with Nitro Boosts
3) Spam right click on your equipped boots, and you shouldn't loose the rocket boost effect. Alternatively, you can use a macro and bind it to a key.
