A ski for use on ice or snow is disclosed. The ski includes a ski body having a tip portion, a tail portion, and a longitudinal running length extending between the tip portion and the tail portion and a substantially flat bottom surface for sliding on snow or ice. The ski also includes a suspension system comprised of a substantially rigid support structure secured to the longitudinally central region of the said ski body at two attachment locations separated by a distance of at least 5 inches along the longitudinal axis of the ski body, and at least one resilient element configured to exert an opposing force between the support structure and the ski body in the area between the two attachment locations.

A ski gripping system has a ski, a gripping strip and a piece of skins. The gripping strip is mounted longitudinally and laterally to an outer side of the ski along a center portion/grip zone of the ski. A width of the gripping strip is from 17 mm to 60 mm, a height of the gripping strip is from 15 mm to 25 mm, and a length of the gripping strip is from 600 mm to 800 mm. A longitudinal bottom inner edge of the gripping strip is level with an underside of the ski. An underside of the gripping strip is laterally outward sloping 5 degrees upward relative to the underside of the ski. The piece of skins is attached to the underside of the gripping strip.

A ski having a core that includes a left lateral edge, a right lateral edge, and at least one central inner core positioned between the two lateral edges. The core also includes a plurality of left wings arranged between at least one central inner core and the left lateral edge, each left wing forming an angle between 5 and 85 or between 95 and 175 with the longitudinal axis X, and a plurality of right wings arranged between at least one central inner core and the right lateral edge, each right wing forming an angle between 5 and 85 or between 95 and 175 with the longitudinal axis X.

A snow riding implement includes a top face, a bottom face, a tail portion, a tip portion, and a midportion. A core of a first material extends from the tail portion to the tip portion. A sidewall extends between the top face and the bottom face and is formed from a second material different than the first material. The sidewall has a first side portion, a second portion and a third portion. The first side portion extends along the midportion at a first angle oblique to the bottom face, wherein the first side undercuts core. The second side portion extends along the tail portion at a second angle, different than the first angle, relative to the bottom face. The third side portion extends along the tip portion at a third angle different than the first angle relative to the bottom face.
