Deflection of the ski, ski-snow contacting pressure, boot-ski loads have been measured during the turn on the snow slope on the two skis of different bending stiffness distribution. The result shows that the ski-snow contacting pressure distribution is different in spite of that boot-ski loads and ski deflections are similar in the same carving turn remaining the same snow groove. From the deflection data, snow groove dimensions and measured pressure distribution, ski-snow contacting situation have been estimated by the correspondence between the deflected edge line with edged ski sliding surface and the snow groove surface. The idea that the front part of the ski bends to compress the snow surface and rear part of the ski rides on the formed snow groove surface is validated from the investigation. The difference of the ski-snow contacting pressure distribution attributes to the difference in the bending stiffness distribution of the ski.
