Non edge locked carving is essentially carving using very high edge angles on the inside ski (lots of LTE tipping) , but keeping the angle on the outside ski at a much lower angle so it will not edge lock and track. It will actually lightly brush through the turn. This gives incredible speed control and a greater ability to exit the turn (edge locked can be hard to exit mid turn especially off piste whe the terrain is not uniform). This greater ability to exit the turn, allows for SRT's in steeper terrain at speed. Essentially the brushing acts as a mild speed deterent , but really what controls the speed is the short radius nature of the turns as each one blocks speed from building up. The flexion aspect is using the flexing of the legs (knees bent deeply) as a means to release the ski. This is simply following the physics of motion. If you wnat to go faster on a cat track, the sure fire way is to get in a tuck. In this position you are taking pressure off your edges (you are also getting your weight back). Hence with less friction you move down the fallline faster. The same thing happens when you bend the knees in transition. The edge presusre is released (you also move back some on the ski which releases any tip pressure) therefore the skis are in the best position to transition to the the new set of edges. In this type of turn this is accomplsihed by the tipping of the LTE of the new inside ski and holding back from engagement of the new BTE. Some angle will naturally occur on the new downhill ski, buit I actively hold back the adge angle. This produces a brushed carved turn that will release at any moment. It also allows carving movements in off piste terrain, as shown in the videos.
