Kalliorinne, K., Hindér, G., Sandberg, J., Larsson, R., Holmberg, H.-C., Almqvist, A. “...As in all endurance sports, cross-country skiing requires the use of energy to overcome resistive forces, in this case primarily aerodynamic drag and friction between the skis and snow. Even a slight reduction in either of these can determine the outcome of a race. ...”

Sandberg, J., Hindér, G., Holmberg, H.-C., Almqvist, A., Larsson, R. “...While the mechanisms of friction are discussed, a complete understanding of these mechanisms has not yet been reached....”

Michalek, A. J. “...The purpose of this material is to maintain a low coefficient of dynamic friction at low contact pressures, while plastically deforming to conform to the snow surface (resulting in a high coefficient of static friction) at high contact pressure. ...”

Hindér, G., Sandberg, J., Kalliorinne, K., Holmberg, H.-C., Almqvist, A., Larsson, R. “...This study evaluates the negative effects of grip wax application on the dynamic ski-snow coefficient of friction and subsequent performance during the double poling cycle in cross-country skiing. ...”

Quirion Cantin, N., Lépine, J., Bégin-Drolet, A. “...This study examines the effective static coefficient of friction of cross-country skis on snow, using an on-site linear tribometer. ...”

Auganæs, S. B. “...A decisive factor for performance in cross-country skiing is the friction between the ski and snow. As a consequence, a lot of effort is put into developing fast skis and glide products. ...”

Kalliorinne, K., Sandberg, J., Hind´er, G., Holmberg, H. C., Supej, M., Larsson, R., Almqvist, A. “...Friction...”

Kalliorinne, K. “...The present work focuses on the resistive force of friction between the ski and the snow. At the highest level of ski sports, a signifcant efort is made to reduce the ski-snow friction, and a slight reduction in friction can signifcantly impact the race outcome. ...”

Kalliorinne, K. “...The present work focuses on the resistive force of friction between the ski and the snow. At the highest level of ski sports, a large effort is made to reduce the ski-snow friction, and a small reduction in friction can have a large impact on the race outcome. ...”

Yu, Z., Liu, Y., Hao, Y., Wu, Y., Liu, Y., Zhou, F. “...Friction on snow surface, especially in relation to winter sports, is difficult to measure directly because of its complexity and variability. ...”

Kalliorinne, K., Hindér, G., Sandberg, J., Larsson, R., Holmberg, H., Almqvist, A. “...For instance, one dominant resistive force in connection with cross-country skiing is the friction between the skis and snow and since the 1930s, research designed to understand and reduce this friction has been ongoing. ...”

Mössner, M., Schindelwig, K., Heinrich, D., Hasler, M., Nachbauer, W. “...Modeling of ski friction requires an in-depth understanding of the ski-snow contact. ...”

Scherge, M., List, S., Hollenbacher, J. “...Force differences between left and right skis are accompanied by different frictional forces. As a consequence, the athlete experiences a twist along the vertical body axis, which has a detrimental effect on the propulsive force during double pole skiing. ...”

Mössner, M., Schindelwig, K., Hasler, M., Nachbauer, W. “...INTRODUCTION: Snow friction is a major performance factor in cross-country skiing 1. ...”

Gløersen, Ø., Hoel Rindal, O. M., Tjønnås, J. “...Rated "glide" was compared to ski friction coefficient, which was estimated in a downhill segment by considering changes in mechanical energy and estimating air drag. ...”

Guo, S., Love, G., Brown, C. A. “...It is not known what characterizations might be pertinent for characterizing base structures for correlating with friction. It is suggested that recent work on multiscale curvature characterizations for feature shape and anisotropy might be useful as well as multiscale volumetric capacity, like filling scale....”

Hasler, M., Jud, W., van Putten, J., Nachbauer, W. “...INTRODUCTION: For many years, frictional meltwater was the assumed explanation for the low friction on snow. ...”

Hladnik, J., Supej, M., Jerman, B. “...W_tot was obtained by summation of W_seg and the work done against friction (W_env) (Hladnik et al., 2016). RESULTS: TME_seg was 5.6% greater than TME_com. ...”

Auganæs, S. B., Buene, A. F., Klein-Paste, A. “...METHODS: Firstly, the friction of a cross-country ski was tested by altering the binding position 10 cm in front and behind the normal position. ...”

Buene, A. F., Auganæs, S. B., Klein-Paste, A. “...Silicones are affordable, low-toxic and hydrophobic compounds which may be useful glide enhancers to reduce ski-snow friction. METHODS: We tested a range of silicone oils with viscosities of 10-100 cSt. ...”
