Abstract: The presently disclosed subject matter is directed to a pair of skis that exhibit increased speed compared to prior art skis. Specifically, each ski exhibits a reduced projected frontal area to decrease drag force (and thereby increase speed). Each ski includes a plurality of parallel air tunnels that run along the length of the ski from the front end to the rear end. The tunnels enable a significant portion of the air that contacts the front end of the skis to simply pass through the skis.
