Abstract
Abstract A ski boot construction comprises a ski boot sole having a bottom substantially planar face with a recess defined in the face centrally between a front sole portion and a rear sole portion forming a heel. A walking aid comprises a member which has a face engageable over the front face portion and an opposite ground engaging face which projects outwardly from the front portion, providing an abutment to raise the front portion off the ground in a walking position so as to cause the vertical center line of the boot to shift to a substantially vertical position. The walking aid is mounted so that it may be moved, for example, pivoted, so that it becomes disposed in the recess between the front and rear portion of the sole, so that the sole defines a surface which again orients the boot so that the center line of the boot is disposed so that it tilts forwardly from the vertical for skiing.

Claim 12
Dependent Claim
103 words
A ski boot construction, comprising a ski boot sole having a bottom substantially planar face, a recess defined in said face intermediate the length of said sole, said sole having a front sole portion in front of the recess, a walking aid comprising a member with one face engageable over said front portion and an opposite ground engaging face projecting outwardly from said front portion so as to raise said front portion off the ground in a walking position, said member being of a size to be accommodated in the recess and being positionable in the recess in an inoperative position for skiing.
Claim 13
Dependent Claim
