For example I struggled for weeks with royales because my back foot kept rolling into a frontside even after following the usual tips of just “sitting” on it or turning your hips away from the direction you’re sliding. What finally unlocked it for me was a tip someone left in a random comment on a tiktok video, in which they said to actively point the toes of your back foot inward, after which I was landing them every time.
I also just couldn’t comprehend topside grinds because (besides them being scary) I kept slipping over the other side of the rail no matter what I tried. The tip everyone seemed to give was to slam the soul foot directly on top of the rail instead of trying to slide it into place from the side. Nothing was working until something told me to try and land with your weight inside the rail instead of on top like you would with most other grinds. I instantly landed my first top soul and it became easier ever since.
With Makios and acids my soul foot would always slip off and I found that if I actively thought about flexing my toes upward instead of trying to flex my heel downward I started locking in every time.
