Abstract: Support devices for the shanks of skier's legs wherein levers on opposite sides of and parallel to the shank are pivoted about an axis at ankle height and secured to the shank just beneath the knee by a flexible strap. Two rods are pivoted to the lever arrangement on each side. In the case of a single lever the rods are pivoted above and below the lever axis. For parallel levers one rod is pivoted above the axis of one lever and the other rod below the axis of the other lever. In each case the rods pass through a resilient compressible block. When the shank swings forward a stop on one rod compresses the block, while the other rod moves freely in the opposite direction. When the shank swings backward the roles of the rods are reversed.

Abstract: A support for the lower leg of a skier comprises an arm pivotally connected at one end to the upper part of the lower leg and at the other end to the ski through jaws gripping the ski-boot and firmly connected with the ski by the pressure of the boot sole thereon. Pivoting of the arm is controlled by a double acting resilient device which is adjustable to vary the force on the arm and to vary the neutral position of the arm.
