What it means
A ski turns more cleanly when it is tipped and pressured in a useful way. Edging is the relationship between the ski, the snow, and the body movements that create grip.
Ski metric explainer
Edging describes how the skis are tipped and engaged with the snow to shape the turn.
A ski turns more cleanly when it is tipped and pressured in a useful way. Edging is the relationship between the ski, the snow, and the body movements that create grip.
Good edging helps the skier shape the arc instead of skidding late. It also creates a platform for pressure and rhythm, especially on firmer snow.
Good edging usually builds progressively. Problematic movement may show an abrupt edge set, a late edge change, or skis that stay too flat until the bottom of the turn.
Video cannot measure ski-snow interaction perfectly from every angle, but replay can show leg inclination, edge-change timing, and whether the skis begin shaping before the fall line.
Compare when the new edges engage on left and right turns. Watch if the upper body turns first or if the legs create the edge change underneath a quieter torso.

Edge angle describes how much the skis are tipped relative to the snow, but the useful question is when and how that angle develops.
Pressure is how the skier manages force through the skis as the turn develops and releases.
Parallel shins can be a useful visual cue for leg alignment, edge relationship, and whether both legs are participating in the turn.
