upper body works on steeps with retraction of the lower body.
Foot steering is nice, but I feel the "key" is upper and lower body seperation.
- Upper body stays balanced in the direction of travel
- Lower body flexes and extends to handle the what the board is doing
and leading stems from the eyes (where are you going) to the upper body getting balanced to the lower body absorbing the dynamics of the sidecut and reaction to the snow. So for ME I work from the top down not the other way around. But I never passed my instructor exams even though I can always school the schoolers. What do I really know, is just what works for me.
