Disclosed herein is a snowboard deck. The snowboard deck includes a board-shaped deck body on which both boots worn by a snowboard user desiring to enjoy riding in a snowfield are positioned and fixed; a binder hole formed in a hole shape in the deck body and provided with a magnet to fasten and fix the boots worn by the snowboard user with a magnetic force; and the boots provided with metal protrusions connected through the magnetic force from the magnet inserted and fastened into the binder hole.

A system and method for providing a ski-snowboard device capable of skinning in an uphill ski mode and skiing in a downhill snowboard mode. The system may include two skis with inner and outer edges having substantially convex side cuts, and an insert that fits into the space between the inner edge side cuts of each of the two skis. The convex side cuts of the inner edges of the skis may have a groove formed in each, and a mating tongue on each side of the insert can fit into the grooves in a downhill snowboard mode. The tongue-and-groove connection may improve the torsional stiffness of the board, and the convex side cuts may allow a user to better grip when skiing and eliminate the step of switching the skis when used as sides of the snowboard.

A snow and water sport sliding device with a pneumatic core and method of manufacturing the device. The device includes a top layer comprising a front tip, a middle segment with a binding plate, and a back segment with an adjustable air valve. Top layer may also include a blade spring system. The device also includes a main core component layer under the top layer that comprises of a hollow air chamber, and a base layer. Base layer may include embedded metal edge.

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 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 snowboard support apparatus, attached to the snowboard in such a way that it extends from the board and provides a physical support for the rider to lean against in order to aid in the process of learning to snowboard. The support apparatus provides support to the rider to allow them to develop skills in being able to ride a snowboard in an incremental and natural manner without constraining the riding experience.

A ski, wherein the ski includes: a ski core; a ski coating which forms an underside of the ski; a lower flange which is arranged between the ski core and the ski coating; steel edges; and side walls; wherein the lower flange includes at least a front region and/or a rear region which is broader, in a direction transverse to a longitudinal axis of the ski, than a distance between the steel edges in the direction transverse to the longitudinal axis of the ski in the region.
