211 Developing an active inside (rear) leg
More often than not, riders have difficulty with skidding on the heelside turn. Skid is the result of too much weight (pressure) on the front end of the board. Typically, the front foot is over-weighted on a heel-side turn. At the same time, the front knee is often rolled towards the new turn, twisting the board lengthwise. This means that as soon as the turn begins, the tail of the board has both less bite, and less pressure. In order to clean up the skid, a means of countering these tendencies is required.
Due to the myriad stance options, it is better to state the goal rather than an absolute fix.
(Assume a medium to long turn, so that there is enough time to figure out what is going on. Tracking across the fall-line will also test the effectiveness of the task at hand).
First, overemphasize the weight distribution to the rear foot prior to rolling off the toe edge. Hopefully this will leave you right in the middle of the board. Second, consider tipping the board with the rear foot before the front foot. Again this will leave the board on a more even keel, rather than being twisted.
So, to recap; weight towards the rear foot, tilt board with rear foot, make heel-side turn.
If, by chance, you are riding on sane angles, which is to say, forward facing with both feet, then follow this sequence. (this was devised at 60 degree angles, so figure that the effect will not be absolute at lower angles)
At the exit of the toe-side turn: Contract the hamstring muscle of the rear leg, as though to pull the heel to the gluteus. Then, drop the rear heel, aiming to compress the foam between the Achilles tendon and the medial (inside) ankle bone. Try to feel the heel-side edge bite under the rear foot and then the front foot. Va-va-vroom.
With a little luck, the heel-side turn will have a little more bite and a little less skid. Another consideration here is the relationship of the torso relative to the feet. If the torso is twisted such that the shoulders are turned further forward than the angle of the front foot, the posture becomes muscularly convoluted, and torsional energy is stored in the torso that has no actual function at this time. Turning the torso forward also tends to lift the rear heel. In order to restore contact under the rear heel, a concerted effort must then be made to sit back a bit.
After a fashion, proper weight distribution and edging movements should take place without directing too much thought at the process.
