You Don’t Need to Kick Your Front Foot Far Forward
Mechanism / Why It Happens
Once the front foot leaves the board, its role is done—anything after is just inertia
As you can see from the fact that even hands or fingers can flip a board, the force required to flip it is extremely small. You may often see skilled skaters doing kickflips while kicking their entire leg forward, but when focusing purely on flipping the board, the role of the flick ends once your front foot passes the nose. Any further forward motion of the leg is simply inertia from the initial movement. That’s why if you push your foot too far forward like in the video, the board will just shoot forward and won’t flip. Here’s a practice method for improving front foot control. (Link)
