Super Phantom Move, by Harb Ski Systems, used by World Cup Skiers.

Look at the third, middle frame, he's standing on the little toe edge at the end of the arc.

One of the key moves taught in PMTS Direct Parallel, is the Super Phantom, which means transfer to the uphill edge of the inside ski at the end of an arc. This is accomplished by, reducing the pressure on the outside or stance ski by flexing the leg and or retracting that leg. This causes a release and a strongly balanced entry to the new arc.
