Abstract
Abstract A simply constructed skiing aid device is disclosed comprising a molded form-fitting brace or insert which fits between the skier''s foot and back part of the ski boot and extends upwardly to embrace the back or calf part of the leg. The device is contoured to fit the calf muscle comfortably and the lower portion is narrow to fit and move about the Achilles heel so that by leaning backward thereagainst the weight upon the front of the ski is lessened for better control of the tip of the ski in maneuvering and reduction of snow penetration.
