The parallel turn in alpine skiing is a method for turning which rolls the ski onto one edge, allowing it to bend into an arc. Thus bent the ski follows the turn without sliding. It contrasts with earlier techniques such as the stem Christie, which slides the ski outward from the body ("stemming") to generate sideways force. Parallel turns generate much less friction and are more efficient both in maintaining speed and minimizing skier effort.
Parallel turns require solid contact from the skier's lower leg to the ski to rotate it on-edge. This was difficult to achieve with early ski equipment, limiting the technique to the high performance realm of racing. The introduction of composite skis, metal edges, releasable clamping bindings, and stiff plastic boots combined to allow parallel turns even on beginner equipment. By the late 1960s it rapidly replaced stemming for all but very short-radius turns. The evolution of shaped skis in the 1990s advanced the carving turn to preeminence.
Today parallel turns are taught to teach novice skiers the effect of weighting and unweighting their skis.

“The universe expects every man to do his duty in his parallel of latitude.”
—Henry David Thoreau (1817–1862)
“Peter the Hermit, Calvin, and Robespierre, sons of the same soil, at intervals of three centuries were, in a political sense, the levers of Archimedes. Each in turn was an embodied idea finding its fulcrum in the interests of man.”
