Abstract: A ski or snowboard has a lower running surface and comprises means for attaching a boot to the ski or snowboard, a deformable lubricant reservoir, and means for conveying lubricant from the reservoir to the running surface, the arrangement being such that, in use, an attached boot can exert pressure on the reservoir to deform the reservoir and drive lubricant from the reservoir, via the conveying means, to the running surface. The means for conveying lubricant is preferably arranged to convey lubricant from the reservoir to a plurality of positions on the running surface, via one or more porous members that each have an outer surface which forms part of the running surface. A corresponding lubrication method is described.
