A snowmobile ski having a front portion the bottom of which is slightly concave. On each side of the middle portion of the snowmobile ski there is a downwardly extending longitudinal side portion. At the front of each downwardly extending longitudinal side portion are located a forward-facing horizontal wedge and a forward-facing vertical wedge. At the rear of each downwardly extending longitudinal side portion are placed a rear-facing horizontal wedge and a rear-facing vertical wedge. A flexible loop is attached to, and mounted flush with, the bottom of the front portion of the snowmobile ski. The flexible loop curves in front of, and above, the front portion of the snowmobile ski, before being slidably attached to the top of the front portion of the snowmobile ski. The middle portion of the snowmobile ski is thicker than either the front portion or the rear portion of the snowmobile ski.
