ABSTRACT:
A sport shoe device which prevents dorsiflexion or plantar flexion of the ankle past a predetermined optimum angle, while permitting tightening on the instep during further flexion of the leg relative to a ski boot contact surface. The device is preferably used with a ski boot including a sole, a shell defining a foot section connected to the sole and cuffs defining a leg section connected to the shell for forward and rearward movement of the cuffs relative to the shell. Overlying the sole is a movable footbed. The footbed is operatively connected to the shell, cuffs and instep strap by a yoke and cable or spring. Movement of the leg and cuffs relative to the foot and footbed beyond a predetermined angle pivots the footbed, tightening the instep strap on the instep while maintaining the predetermined flexion angle during further flexion.
