Hi guys, hoping to use english words in a correct way and making sense (if so... sorry).
I would say that it is not necessary to give pressure on the sole of the foot, but more to firmly hold the edge of the skis (inside and outside, both). if I want to try to give some kind of pressure, it should be on the edge, as if the intention was to use it to cut the ground. anyway probably the word pressure can be confused as if you meant a push, instead of a cut; Especially those who have learned to ski with the old school (like me) remember the pressure against the ground given by the extension phase, before the change of edges. For this reason imho the term pressure can generate some problems on its significance with current skiing... the combination of ski deformation and sidecut radius will do their job without the skier having to give extra pressure compared to that which is already naturally brought into play. The more cut I can give, the greater the deformation and the more the curve will be closed. I think that if the movement is well executed, the weight will naturally go mainly to the external foot. The greater the slope and speed, the greater the load on the outside.
my 2 cents

PS obviously all this refers to curves without skidding on enough compact snow
