Abstract
Abstract A walking method and apparatus for ski boots is disclosed wherein a walking member is detachably affixed to the sole of the ski boot. The walking member has a sole portion for engaging the walking surface and an upper portion for supporting and being affixed to the sole of the ski boot. The walking member depends from the sole of the ski boot and is shaped to provide a forward rocking motion for the ski boot during the user''s normal stride. The point of engagement of the sole of the walking member with the walking surface is generally confined to a region below the ski boot and between the ball of the foot and the ankle to relieve walking stresses on the ankle of the user.

Claim 1
Independent Claim
294 words
In a walker for ski boots, body means having a bottom sole portion for engaging a walking surface and an upper portion for engaging the sole of the ski boot for supporting the weight of the user, said sole of said body means having a toe portion to engage the walking surface and disposed such as to be positioned below and generally in the region of the ball of the foot of the user and said sole having a heel portion to engage the walking surface and disposed generally in the region below the ankle of the user, said toe and heel portions depending downwardly from the sole of the ski boot by relative amounts such that said body when supporting the ski boot in the horizontal position has both said toe and heel portions of said sole of said walker body in supportive engagement with the horizontal walking surface to prevent rocking of the ski boot when the user is standing stationary, and wherein said toe and heel sole portions of said body means depend downwardly by an extent such that when said walker body is inclined at an angle to the horizontal walking surface corresponding to the forward-most position of the user''s stride, the heel portion of the sole of said walker body and the heel portion of the ski boot are in approximately the same horizontal plane, and when said walker body is inclined at an angle to a horizontal walking surface corresponding to the rearwardmost position of the user''s stride, the toe portion of the sole of said walker body and the toe portion of the ski boot are in approximately the same horizontal plane, whereby said walker body substantially reduces walking torque transmitted to the ankle of the user.

In a walker for ski boots, body means having a bottom sole portion for engaging a walking surface and an upper portion for engaging the sole of the ski boot for supporting the weight of the user, said sole of said body means having a toe portion to engage the walking surface and disposed such as to be positioned below and generally in the region of the ball of the foot of the user and said sole having a heel portion to engage the walking surface and disposed generally in the region below the ankle of the user, said toe and heel portions depending downwardly from the sole of the ski boot by relative amounts such that said body when supporting the ski boot in the horizontal position has both said toe and heel portions of said sole of said walker body in supportive engagement with the horizontal walking surface to prevent rocking of the ski boot when the user is standing stationary, and wherein said toe and heel sole portions of said body means depend downwardly by an extent such that when said walker body is inclined at an angle to the horizontal walking surface corresponding to the forward-most position of the user''s stride, the heel portion of the sole of said walker body and the heel portion of the ski boot are in approximately the same horizontal plane, and when said walker body is inclined at an angle to a horizontal walking surface corresponding to the rearwardmost position of the user''s stride, the toe portion of the sole of said walker body and the toe portion of the ski boot are in approximately the same horizontal plane, whereby said walker body substantially reduces walking torque transmitted to the ankle of the user.
Claim 3
Dependent Claim
20 words
The apparatus of claim 1 including strapless means for detachably affixing said walker body to a ski boot for walking.
Claim 4
Dependent Claim
64 words
The apparatus of claim 2 wherein said means for affixing said walker body means to the ski boot comprises horizontally directed pin means on opposite sides of said body and carried from said walker body for engaging horizontally directed bores in the sole of the ski boot or structure affixed to the sole of the ski boot on opposite sides of the ski boot.
Claim 5
Dependent Claim
40 words
The apparatus of claim 3 wherein said pin means on one side of said walker body is spring biased to engage a corresponding bore in the sole of or in the structure affixed to the sole of the ski boot.
Claim 6
Dependent Claim
24 words
The apparatus of claim 1 including an elastic tread means disposed on said sole of said walker body for engagement with the walking surface.
Claim 7
Dependent Claim
183 words
In a walking apparatus for use with ski boots to relieve walking stress on the users ankle, walking means for attachment to the sole of the ski boot to depend below the sole of the ski boot for engaging the walking surface to support the ski boot and user for walking and standing, said walking means being dimensioned and shaped for providing during a normal stride a forward rocking motion of the ski boot about a point or points of engagement with the walking surface, which point or points of engagement lie intermediate the ends of the ski boot for reducing the torque transferred via the ski boot to the ankle of the user during a normal walking stride, said walking means including a connecting structure disposed facing the sole of the ski boot, said structure including upwardly extending side portions to extend adjacent the side edges of the sole of the ski boot, and strapless means for interconnecting the side portions of said connecting structure with the sole of the ski boot for detachably attaching said walking means to the ski boot.
Claim 8
Dependent Claim
183 words
In a walking apparatus for use with ski boots to relieve walking stress on the users ankle, walking means for attachment to the sole of the ski boot to depend below the sole of the ski boot for engaging the walking surface to support the ski boot and user for walking and standing, said walking means being dimensioned and shaped for providing during a normal stride a forward rocking motion of the ski boot about a point or points of engagement with the walking surface, which point or points of engagement lie intermediate the ends of the ski boot for reducing the torque transferred via the ski boot to the ankle of the user during a normal walking stride, said walking means including a connecting structure disposed facing the sole of the ski boot, said structure including upwardly extending side portions to extend adjacent the side edges of the sole of the ski boot, and strapless means for interconnecting the side portions of said connecting structure with the sole of the ski boot for detachably attaching said walking means to the ski boot.
Claim 9
Dependent Claim
47 words
The apparatus of claim 6 wherein said means for detachably affixing said walking means to the ski boot for walking also includes means for detachably attaching said walking means to the upper surface of a ski for storage while the ski is in normal use for skiing.
