Patent attributes
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 concave side cuts, and an insert that fits into the space between the inner edge side cuts of each of the two skis. The concave 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 concave 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.
