One of the most important factors in evaluating the performance of a ski board is its sliding performance. In order to improve sliding performance, it is necessary to reduce sliding resistance. Sliding resistance is affected by the physical properties of the surface material and wax, as well as the shape of the surface. In this study we have investigated the influence of microgrooves, called "structures", on the sliding performance in order to improve the sliding performance. The relationship between the coefficient of friction and the ice temperature was investigated quantitatively. The results of the friction experiments indicate that when the temperature inside the freezer was -25°C, the static friction coefficient was lower with the structure compared to without the structure. Both the static friction experiment and the dynamic friction experiment showed this trend. Additionally, the dynamic friction experiment demonstrated that the coefficient of dynamic friction was lower with the structure at both -20°C and -25°C inside the freezer.
