Abstract
Abstract A ski boot is constructed with a relatively rigid bottom foot enclosure, a somewhat more flexible cuff portion pivotally connected to the foot enclosure at the axis of the ankle, and an even more flexible spat portion arranged to close over the upper portion of the foot. A bottom traction surface comprised of heel and sole portions is removably connectable to the boot. The bottom of the foot enclosure and the traction element are mutually adapted to provide a variable cant for the foot enclosure with respect to the bottom of the traction element. A removable inner boot of soft cellular foam material is provided within the foot enclosure, and is slit down the front to facilitate foot entry without a tongue. The inner boot is also provided with external spacing tabs in the vicinity of the lower ankle to ensure a snug fit around the heel. The cuff portion is releasably engageable by a spring biased connector located at the back of the boot. Forward pivoting of the cuff with respect to the foot enclosure is guided by a pin extending from a wall of the foot enclosure through a slot in the cuff. This slot may be partially filled by a suitable insert to restrain backward movement of the cuff.
