poser
What it means
The cue usually refers to the lower legs showing a similar angle while the skier edges through the turn. It is a simplification, but it can help spot a passive inside leg or mismatched edging.
Ski metric explainer
Parallel shins in skiing
Parallel shins can be a useful visual cue for leg alignment, edge relationship, and whether both legs are participating in the turn.
Why it matters
When the lower legs work together, the skier often has a cleaner platform and better ski relationship. When they diverge sharply, the inside ski may wander or the skier may over-rely on the outside leg.
Good vs problematic movement
Good movement may show the shins changing angle together as the skis tip. Problematic movement may show the inside knee collapsing, the inside ski flattening, or a wedge-like relationship in parallel terrain.
How Poser can visualize it
Skeleton overlay can make lower-leg relationships easier to see, especially when clothing hides knee and ankle movement. It is a visual estimate and should be checked against the original video.
What to look for
Watch the middle of the turn and compare both sides. Look for whether the inside leg supports the turn or simply follows after the outside ski has already done the work.

Edging in skiing
Edging describes how the skis are tipped and engaged with the snow to shape the turn.
Edge angle in skiing
Edge angle describes how much the skis are tipped relative to the snow, but the useful question is when and how that angle develops.
Steering in skiing
Steering is how the skier guides the skis through direction changes, usually with the legs working underneath a stable upper body.
