But to answer your question;
You can try this without your boots on:
When going heelside imagine curling / flexing your toes upwards. Your weight will naturally distribute on to your heels. Now imagine going toe side by lifting your heels and your weight will naturally distribute onto your toes.
Now try it with boots and bindings on. The boots and bindings will prevent you from doing the forementioned but it well definitely give you the mental layout you need to engage these turns
