Balance
The balance point is the center of your weight relative to the surface of the board. Try this: at a standstill, position the board so that it is perpendicular to the slope and you are facing downhill. Now, tilt the toe edge of the board up and down using your ankles, and move yourself front and back until you find the spot where you won’t tip over. That’s your balance point.

The balance point changes with the softness of the snow because in soft snow, you’ll have to tilt your board away from the incline more than you would on hard-packed snow. Try going heelside slowly down an incline by reducing the pressure applied by your heels.
