Scientific breakdown of Treflip
You don't have to use your front foot in a Treflip. But what does it mean? Does that mean you don't have to pay attention to your front foot because it does something unconsciously, or the front foot indeed does nothing?
This page will discuss objective and scientific reasons why a Treflip flips and why you don't have to use your front foot.
Summary
Your front foot does NOT flip your board in treflip.
Your front foot loses contact with your board before your back foot completes a scooping sequence. Use your front foot to hold your weight when crouching but not to flick.
Stored energy flips the board.
The rear bushings flip the board by trying to return to their original state after being pushed down. Scoop the tail around the vertical axis(z-axis) to effectively squeeze the bushings.
Scoop = Twisting back foot inward
Focus on twisting your back foot inward around the vertical axis(z-axis), and your board flips sufficiently. Avoid swinging it to the heel side or pushing it toward your front foot.

Why does a Treflip flip?
Common Misconception
You may assume you must do a 360 Pop Shove-it with your back foot while making a Kickflip motion with your front foot.
However, a 360 Kickflip flips due to entirely different mechanics.
A reason the front foot doesn't flip the board
As you look closer at my front foot, you can see it leaves the board even before my back foot finishes scooping, making it impossible for my front foot to flick my board.
How a back foot flips the board.
Being the last element to stay in touch with the board, the back foot causes the flip. Your back foot's toe side sinks as you twist your back foot around the z-axis, bending the rear bushings like compressing a spring. Consecutively, the bushings store energy to return to their original state once you release the back foot. This bouncing energy causes a flip.
Does the front foot do nothing?
While the front foot does not cause a flip, it plays a vital role in holding your board. Your front foot must hold your board until your back foot applies sufficient energy to the tail and squeezes the rear bushings low enough.
How to practice
Focus on the Z-axis rotation.
This time, we focus only on the most crucial part: twist around the vertical axis= the Z-axis rotation.
Utilizing the bouncing force of rear bushings is the most vital part of my type of Treflip. Turning your back foot inward around the z-axis (what they call the "Scoop") will cause both a 360 Pop Shove-it rotation and the Kickflip rotation.
And you don't need to swing your back foot to the heel side intentionally, as the weight distribution strongly affects the horizontal spin; Shifting your weight on the toe side before popping allows your back foot to push the tail to the heel side by popping straight down.

The Science of Treflip in Skateboarding
Should you learn Treflip after Varial Flip?
Do I have to learn Varial Flip before Treflip?
No. They flip due to fundamentally different mechanics.
This article analyzes the scientific differences between a Varial Flip and a Treflip. They rotate and flip for entirely different reasons, and the distinction involves far more than how the back foot moves. Let us examine the mechanics in detail.
Treflip weight distribution and landing back on your board
Why is it easier to Treflip while moving?
Because the board opens up due to the distribution of weight.
In this article, we examine the well-known idea that Treflips are easier when performed while moving. Many skaters, including myself, find that even a slow rolling start makes the trick far more manageable. But what is the scientific reasoning behind this? One key factor is how motion influences the distribution of weight.
The Function of The Front Foot in Treflip
What does the front foot do in a Treflip?
It stabilizes the board and does NOT flick it.
There has long been disagreement about the role of the front foot in a Treflip. In practice, there is no single correct method, and the usage varies according to each skater’s preference. In this article, I explain how I use my own front foot when performing Treflips.
Key to consistent Treflip - Scoop when your body's going up
Why does your Treflip not flip?
Because your body is holding the board down.
Some skaters can Treflip or Shove-it with remarkable lightness. Understanding the mechanism behind a steezy Treflip helps you achieve the same. The central question explored in this article is: Can you truly scoop the board if your entire body is pressing it downward?
