Ski deflection with its torsion and the ski-snow contacting pressure have been measured simultaneously during the actual turn on the snow surface. Ski deflection and the torsion were measured by the deflection sensor beam that was developed by the authors. Ski-snow contacting pressure was measured applying commercial pressure sensors. In the long carving turn on the well pressed snow surface, pressure showed a hill distribution that pressures were high around the boot center area. The deflection of the ski in the front side well corresponded with the pressure applied in front of the boot center. The deflection caused by the torsion was small. Applying the average ski deflection profile on the remained snow groove, it is estimated that the region between the top and the boot center area makes the carved groove by partly compressing and partly excluding the snow. The tangents of these surfaces have counter angles with the turn trajectory tangent and the applying pressure on this area produces the turning force.
