Ah, now we get into some interesting concepts! One of the common misunderstandings in lessons is the concept of "get forward." This is often misunderstood by the student as needing to constantly drive into the front of the boot cuffs. This brings the skier into an unbalanced position on the balls of the feet through the shaping and finishing portion of the turn and usually produces the effect of the skier dropping his/her bottom to compensate for the resulting instability.
(One note: "Stroking the ski" from tip to tail by rolling forward and back along the bottom of the foot throughout the turn is totally different. The problem arises when the skier is encouraged to stay leaning forward on the balls of the feet past the initiation phase, and/or constantly drive into the front of the boot.)
Imagining you are constantly balancing on a rubber mat on top of your skis with no binding to support you encourages a constantly shifting and stable balance point on the bottoms of your feet. Skiing with your boots unbuckled helps create the same sensation.
Raising the front of the foot has the effect of closing the ankle joint. It engages the muscle in the front of the shin (the tibialis anterior) and automatically brings you forward in to an effective, not imposed, ski position. It also allows you to feel that you are standing and pressing off the strongest part of your foot: the calcaneus bone at the front of your heel bone, right underneath the tibia where it meets the ankle joint. Your body wants to be stable, so you will find that pressing off this portion of the outside-foot heel throughout the shaping phase of the turn will actually feel pretty good! You can find that position by doing one of several movements: Stand on one foot and lift the front. Hop up and down. Where do you automatically land? Also, if you do squats in a gym, where on the bottoms of your feet do you press off? Your body is pretty smart. It will will stabilize you and have you stand on the strongest part of your foot if you don't get in its way!
Hope this helps clarify some important points!
Best!
