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 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. Electric drive motors are provided for selectively positioning said stops. Manually operated control means, attached to the body of the user, are provided for controlling said electric drive motors.
