Abstract

Abstract A ski boot having an upper which is partially journalled on a shell base. The upper includes a front and rear portion. The front portion or cuff is adapted to flex forward with respect to the shell base. Also provided is a control means for controlling the rigidity and flexional characteristics of the boot. The control means includes a flexion band having an arch which extends over the instep of the boot, and also includes two substantially horizontal lateral arms each attached to one end of the arch and extending over each lateral side of the shell base. Each lateral arm is connected to the bottom front portion of the cuff. The arch comprises a first deformation zone and the two lateral arms comprise second deformation zones. The flexion band also includes a means for maintaining a portion of the flexion band in a fixed position with respect the shell base. This means is positioned substantially in a zone in which the arch is connected to each lateral arm. In addition, the cuff also includes a groove, above the flexion band, which extends across the instep of the boot. A cursor is adapted to be displaced at any position along the groove to transmit the flexion force from the lower portion of the cuff to the flexion band.
