ABSTRACT:
A ski boot comprises a rigid outer shell and an inner shell which is relatively flexible. The inner shell features a relatively flexible saddle region which extends over the metatarsal and/or instep portions of a wearer's foot. Tensile elements, such as cables or straps, cooperate with the saddle to provide a variable supporting force to the wearer's foot. The tensile elements extend from the saddle, under the sole of the inner shell and terminate on the heel spoiler. This construction enables a foot supporting tensioning force to be applied to the tensile elements by pivoting the heel spoiler to the closed position. The tensile elements are slackened and the foot supporting force is released as a result of opening the heel spoiler.
In another embodiment the ski boot features a hinged inner sole. The inner sole is secured to the outer shell in the phalanx region of the sole, and also is hingedly connected to the heel spoiler in the heel region of the inner sole. A hinge, either mechanical or natural, is disposed adjacent to or in common with the fastening point. The hinge enables heel, arch and metatarsal regions to pivot relative to the phalanx region of the sole to improve the ease of foot entry and exit.
