A hinged ski boot comprising a lower shell, continuous with an unsupported soft upper shell, forming one continuous compound shell. The rigid lower shell has a forwardly located reinforced area for engagement of the front ski binding and a control linkage. The lower rigid shell has a recessed rearwardly located reinforced area for engagement of the rear ski binding and shaft hinges. A skeletal shaft, front cuff and rear cuff form one continuous portion, devoid of fastening means and is hingedly secured to the lower rigid shell. A tubular control linkage connects the front of the rigid shell to an intermediate portion of the shaft. This control linkage provides both forward and rearward flex control, provides flex progressiveness, provides a flex biasing, limits maximum ankle movement, provides forward-lean adjustment and comprises a piston air pump, actuated by ankle flex, to draw cold stale air from the front of the shell cavity. The combination of a rigid lower shell and a non supported soft upper shelf reduces unwanted air invasion into the shell cavity and provides a non critical shaft hinge location. The structure of the ski boot is both weight efficient and energy efficient.
