Board Performance
By understanding the way a snowboard performs, an instructor can accurately describe what should happen or what is actually happening to the board in any given task.
To fully understand how edging, pressuring and steering work in relation to the turn or a trick, it is necessary to have a knowledge of the side-cut, length, camber profile and flex of a snowboard (see Snowboard Equipment for further reading).
Edging
Edging is used to increase and decrease grip on the snow surface. During the initiation of a turn, edging in the snowboard must decrease, or flatten to allow it to change edges. In effect, this is the edge angle of the board reducing to a flat base before increasing again on the new edge. This may occur as torsional twist to flatten the snowboard at one end before the other, or it may be tilt through the entire running length of the board. Edging of the snowboard will then continue throughout the completion phase of the turn.
The angle and the rate that the board is twisting or tilting will greatly affect the path the snowboard will take, as well as the performance, unless influenced through pressuring and steering.
Here are some key points about edging the snowboard:
It should be noted that edging of the board may need to be completely eliminated at times, especially when riding boxes and rails.
Pressuring
Pressuring is used to create, manage, distribute and release flex and bend in the snowboard. Within a turn, pressure is generally released in the initiation phase to allow for an easier edge change. As the board moves onto the new edge, pressure can be applied from somewhere within the control phase (where exactly depends on the turn) through to the completion phase. Pressure is then released again through the initiation phase.
Pressuring of the snowboard during a turn has a direct relationship to edging. The faster the board travels and the higher the edge angle, the more the board will bend or flex through the forces acting on it (see Turn Forces for further reading). Pressure can also be distributed to different parts of the board, such as the nose, the tail, the centre or throughout the whole board. This is used in many freestyle aspects but can also be applied in turns.
Once pressure has been applied to the snowboard, at some stage it will have to be released. How the pressure is released will affect the overall outcome. Most snowboarding relies on efficient, progressive management and regulation of pressure to suit the task and terrain.
At times, pressure will be the only performance being utilised. For example, in an ollie or nollie, where there is no edging or steering required, just creating a large increase in pressure, flexing the tail of the board, then a rapid release (or rebound) of pressure.

Steering
Steering is used to help direct the snowboard in the desired direction of travel. During a turn, it is best applied once edging and pressuring of the snowboard have begun. Steering is most prominent from the control through to the completion phase of a turn.
The amount of steering that is needed, or can be applied, is directly related to the degree of edge and pressure in the snowboard. In most cases steering begins in the leading half of the snowboard, around the front foot, with the back half following.
