ABSTRACT:
An article of footwear, expecially adapted as a ski boot or hiking boot, has a toe portion and a heel portion respectively having a first and second sole portion that are pivotally rotatable with respect to one another over a fairly large angular range about a hinge between a first position wherein the first and second sole portions are substantially parallel and a second flexed position. The hinged fixedly interconnects the toe and heel portions in a manner preventing relative torsional rotation, and a downward limit stop prevents hyperextension of the foot. An upward limit stop may be included to prevent hyperflexion of the foot. The toe and heel portions may be independent pieces; and a masking panel extends therebetween beneath the foot. Likewise, an upper baffle may extend across the top of the foot between the toe and heel portions. Extension linkage my be employed as part of the hinge.
