Abstract Apparatus used in ski instruction comprising: a pair of spaced horizontal platforms movable back and forth along a given direction in a horizontal plane; a pair of ski boot simulating devices; and a pair of rotatable and vertically movable hinges, each of the ski boot simulating devices being secured by a corresponding hinge to a corresponding platform. The instruction device includes structure whereby each ski boot simulating device is capable of pivoting or rocking from side to side with respect to a vertical axis, and may rotate and move vertically to a limited extent due to the provision of the rotatable and vertically movable hinges by the structure of which the ski boot simulating devices are mounted on their respective platforms. The ski instruction device of the present invention is so constructed and operable as to permit the person undergoing instruction thereon to attain and partake of all of the various movements normally encountered during actual skiing operations.
