ABSTRACT:
A ski base coating including an embossed push-off aid which consists of a plurality of steps having steep gradient push-off flanks (1', 1", 3) in push-off direction and flat angle ramps in gliding direction. The upper side of the steps is formed of a continuous honeycomb arrangement of equilateral or biaxially symmetric hexagonal fields (2', 2"). For improved push-off effect the fields (2', 2") are so arranged that one of the hexagon sides (1', 1") each extends transversely of the push-off direction, that this hexagon side (1', 1") is designed as push-off edge, and that the hexagon faces form the flat angle step ramps. (FIG. 1)
