Abstract: A multi-purpose ski/snowshoe, with a winged frame, an articulated foot plate, and interchangeable bottom surface plugs is described. The multi-purpose ski/snowshoe may be configured in several ways, including a short ski, a short ski with heel-plate brake, and a fully articulated snowshoe. It may be reconfigured by a combination of reversing the winged frame, inverting or interchanging the bottom surface plug, or adjusting the point of articulation. This provides a highly efficient device for foot-powered transportation over a wide variety of winter landscapes.

Abstract: A skishoe having a central, downwardly concave arch portion, an upwardly concave toe portion, an upwardly concave heel portion, and a snow gripping blade. The snow gripping blade is pivotable about an axis lying within the camber of the arch portion and extending transversely of the skishoe. A first adjustable blade stop is provided for limiting the angular deflection of the gripper blade from its fully retracted position in the camber. A second adjustable blade stop is provided for limiting the retraction of the blade into the camber, and a spring is provided for resiliently biasing the blade toward the first adjustable blade stop.
