The idea of carving skis was developed when the question of skidding of the ski was approached from a different perspective. Two basic assumptions were applied: the ski will bend when angulated (angulations is angle between ski running base and snow surface) only to the point when ski center gets in contact with snow surface; the ski will not skid only when all the points of the edge of the ski travel through the same point on the snow surface. If the radius of a turn is chosen together with angulations, then the calculation of the sidecut (intersection of snow and ski surface) is relatively easy. The final result was radical a parabolic sidecut.
