idk if that's a problem, but if you mean that you foot slips off? idk... but try to lean towards the nose when performing a sw heel it helps to keep it under your feet. Ceck my vid

Try not to lean in any direction, keep your balance centered and keep the boards flip straight. This will help you catch the board with better balance. What I did, I learned nollie heels first, they were easier for me.

Thanks riley, im still figuring out but i will land it good soon
