You have to upgrade your dunk attribute and edit your player to select the dunk package you want.

To dunk you have to sprint using RT and hold X when towards up to the basket.
they do not have it for psp but on ps3
First you need a player that has a high dunk rating, like Jordan. You can do a dunk in a game and possibly do a craddle dunk. Im not quite sure if there is a signature dunk that allows you to craddle dunk but you can try.
You may have to upgrade your vertical and dunk attributes, the standing dunk is useful sometimes too.
You have to unlock them until you get them. Apparentely they give +10 dunk. Just keep playing games until you unlock these shoes.
To perform a one-handed 360 dunk in NBA 2K11 for the Wii, first make sure you have a player with a high dunk rating. Approach the basket while holding the Wii Remote and Nunchuk. As you near the hoop, press and hold the 'B' button to initiate the dunk, then flick the Wii Remote in a circular motion to execute the 360 spin. Release the 'B' button to complete the dunk.
You just need a good dunk attribute and vertical attribute.
First of all make sure you have a specialty dunk, then in a game do a dunk, this will do a dunk and it will hopefully do it. Usually happens on a fast break.
You have to have a created player with the 360-between the legs specialty dunk package and then you go to practice and run towards the hoop and then point the analog stick down left diagnal.
Read the manual. I think it is R2 to sprint to the basket and when you get close enough flick the right analogue stick in any direction.
