Roll the ski or snowboard section and follow its contact with the snow.
Tap an edge to lean onto it.
The base lies flat on the snow.
What happens
When the equipment is flat, its base faces the snow. Rolling it shifts contact toward one edge. This cross-section shows that change.
This is equipment tilt, not an edge-tuning angle or a binding setting. The snow is a simplified surface; real contact also depends on snow, pressure and movement.
