Definitions

• the invention relates to a ski, particularly a cross-country ⁇ ski, having a tread layer, wherein the tread layer in a central region, in particular a kick zone, at least two groove-shaped recesses for the attachment of a respective rear slide-inhibiting element has.

If the climbing aids are releasably secured in the recess, this has the advantage that the user can optimize the type of remindgleithemmenden elements as desired for his individual application. If the user moves, for example, preferably on groomed trails it is, for example, using a coated guard band or a sawtooth-like profile band to his progress to optimization ⁇ ren. Moves the user preferably in the free area of the user in the groove may preferably be a fur or the like , arrange.

• the tread layer - seen across the width of the ski - is interrupted and therefore between the lateral boundaries of the recess and the back-inhibiting elements used water can penetrate through the capillary action. This often leads to icing of these areas, whereby a functionality is not guaranteed in practical use.

• Two groove-shaped recesses thus have a front and / or rear end portion, in which - seen transverse to the longitudinal direction of the ski - the other recess (seen in the longitudinal direction of the ski) is not or no longer exists.
• a partial (middle) section is provided by the sectional side-by-side arrangement of the depressions, in which both depressions (viewed in the transverse direction of the ski) run next to one another and thus, when pressure is applied in this region, both return-retentive elements possibly received therein are active at the same time. Accordingly, initially only the remindgleithemmende effect of the element occurs, which is arranged in the groove-shaped recess whose front end is closer to the tip of the ski or whose rear end is located closer to the ski end.
• the remindgleithemmende effect of the other element occurs in an area in which the beginning of the depression is closer to the ski center, during the movement ⁇ expiry only added at a later date, so that a har ⁇ monischer transition between sliding and climbing phase is achieved.
