It's important to practice each step of the trick individually and then work on combining them smoothly to avoid these common mistakes. **

To do a Tre Flip, also known as a 360 Flip, you need to add a kickflip motion to your 360 Shuvit.

At the same time, use your back foot to scoop the board around for the 360 rotation. It may take some practice to get the timing and technique right, but with persistence, you'll be able to land a clean Tre Flip. **
