The present invention concerns a lubricant for improving the gliding properties of skis and its application to skiing. The lubricant possesses an elevated molecular weight but has a very low melting point. Furthermore, the lubricant does not crystallize easily and thus remains oily or waxy also at low temperatures. The lubricant is constituted of four perfluorinated chains attached to a hydrogenated core in a symmetrical arrangement in such a manner that a tetra-substituted derivative or tetrakis derivative is formed according to the following formula wherein each Rx group can be the same or different and comprises a perfluorinated alkyl group.
