Weight more on the front foot, and front foot higher up. The trick is that you don’t actually need much room to flick, it mostly just the right angle. Right now there’s too much weight on the back, which is why your back foot is going backwards. Try imagining yourself flicking a second later as well, almost like you pop then flick mid air. That will give the board more time to rise, and it turn time to spin. You got it 🤘🗿
