Abstract
Abstract A ski boot is provided including a lower sole portion and an upper boot portion supported from and secured to the lower sole portion. The upper boot portion is constructed of stiff material, but includes transverse corrugations extending forwardly and upwardly along opposite sides of the upper and across the instep portion thereof. The corrugations enable forward flexing of the upper portion of the upper boot portion as required to enable a skier to bend his knees and to lean forwardly, and the sole portion is substantially rigid, except in the portion thereof underlying the area of the boot in which the ball of the associated foot is to be received. This portion of the sole is flexible to enable localized flexing of the sole when walking and an attachment is provided therefor operable to selectively render the entire sole substantially inflexible, the attachment being worn while skiing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
153 words
A ski boot including a lower sole portion and an upper boot portion supported from and anchored to the lower sole portion, said boot portion including a forward lower portion for receiving the ball of the user's foot therein, said sole portion, exclusive of the area thereof underlying said forward lower portion, being stiff and substantive non-flexive under normal walking stresses and said area of said sole portion including means rendering said area reasonably flexive for relative angular displacement of the front and rear sole portions forward and rearward of said area about a transverse bending zone to flexed positions with said front and rear sole portions defining and upwardly opening included angle of less than 180°, and an attachment releasably mountable from said sole portion and engaged with said front and rear sole portions rigidifying said sole portion and preventing flexure thereof from a generally longitudinally straight condition to said flexed positions.
Claim 2
Dependent Claim
153 words
A ski boot including a lower sole portion and an upper boot portion supported from and anchored to the lower sole portion, said boot portion including a forward lower portion for receiving the ball of the user's foot therein, said sole portion, exclusive of the area thereof underlying said forward lower portion, being stiff and substantive non-flexive under normal walking stresses and said area of said sole portion including means rendering said area reasonably flexive for relative angular displacement of the front and rear sole portions forward and rearward of said area about a transverse bending zone to flexed positions with said front and rear sole portions defining and upwardly opening included angle of less than 180°, and an attachment releasably mountable from said sole portion and engaged with said front and rear sole portions rigidifying said sole portion and preventing flexure thereof from a generally longitudinally straight condition to said flexed positions.
Claim 3
Dependent Claim
58 words
The combination of claim 1 wherein said sole portion includes at least one longitudinal bore formed therein and extending at least substantially the full length of said sole portion and opening endwise outwardly of the corresponding sole end, said attachment including an elongated stiffening rod removably received in said bore and spanning between said front and rear portions.
Claim 4
Dependent Claim
25 words
The combination of claim 1 wherein said sole portion includes a pair of said bores and said attachment includes a pair of said stiffening rods.
Claim 5
Dependent Claim
62 words
The combination of claim 1 wherein said attachment includes a shallow channel member of greater width than height and including upstanding opposite side longitudinal flanges terminating upwardly in inturned flanges, said channel member being longitudinally slidingly engaged with said sole portion from one end thereof with said inturned flanges overlying upper surfaces of opposite side marginal portions of said lower sole portion.
Claim 6
Dependent Claim
74 words
The combination of claim 1 wherein said attachment includes an elongated rigid plate positionable under said sole portion and including a rear upstanding abutment having a forwardly directed upper end portion for overlying the upper surface of the rear end of said sole portion, the forward end of said plate including a pivoted bail supported over center moveable toggle removably downwardly clamped upon the upper surface of the front end of said sole portion.
Claim 7
Dependent Claim
179 words
A ski boot including a lower sole portion and an upper boot portion supported from and anchored to the lower sole portion, said boot portion including a forward lower portion for receiving the ball of the user's foot therein, said sole portion being stiff and substantially non-flexible, said upper boot portion being constructed of stiff material for lateral bracing of the associated ankle, said upper boot portion including laterally spaced generally parallel corrugations formed therein extending forwardly and upwardly from said sole portion on opposite sides of said upper boot portion and spaced intermediate the opposite ends of said upper boot portion, corresponding corrugations on opposite sides of said upper boot portion being jointed by coextensive upper laterally spaced and transversely extending corrugated zones formed in said upper boot portion extending across the instep portion of said upper boot portion, said corrugations and corrugated zones rendering said upper boot portion flexible to the extent that the upper extremity of said upper boot portion may be flexed forwardly and downwardly relative to the toe area of said upper boot portion.
Claim 8
Dependent Claim
179 words
A ski boot including a lower sole portion and an upper boot portion supported from and anchored to the lower sole portion, said boot portion including a forward lower portion for receiving the ball of the user's foot therein, said sole portion being stiff and substantially non-flexible, said upper boot portion being constructed of stiff material for lateral bracing of the associated ankle, said upper boot portion including laterally spaced generally parallel corrugations formed therein extending forwardly and upwardly from said sole portion on opposite sides of said upper boot portion and spaced intermediate the opposite ends of said upper boot portion, corresponding corrugations on opposite sides of said upper boot portion being jointed by coextensive upper laterally spaced and transversely extending corrugated zones formed in said upper boot portion extending across the instep portion of said upper boot portion, said corrugations and corrugated zones rendering said upper boot portion flexible to the extent that the upper extremity of said upper boot portion may be flexed forwardly and downwardly relative to the toe area of said upper boot portion.
Claim 9
Dependent Claim
120 words
The combination of claim 6 wherein said sole portion, exclusive of the area thereof underlying said forward lower portion, is stiff and substantive non-flexive under normal walking stresses and said area of said sole portion including means rendering said area reasonably flexive for relative angular displacement of the front and rear sole portions forward and rearward of said area about a transverse bending zone to flexed positions with said front and rear sole portions defining an upwardly opening included angle of less than 180°, and an attachment releasably mountable from said sole portion and engaged with said front and rear sole portions rigidifying said sole portion and preventing flexure thereof from a generally longitudinally straight condition to said flexed positions.
Claim 10
Dependent Claim
58 words
The combination of claim 7 wherein said sole portion includes at least one longitudinal bore formed therein and extending at least substantially the full length of said sole portion and opening endwise outwardly of the corresponding sole end, said attachment including an elongated stiffening rod removably received in said bore and spanning between said front and rear portions.
Claim 11
Dependent Claim
62 words
The combination of claim 7 wherein said attachment includes a shallow channel member of greater width than height and including upstanding opposite side longitudinal flanges terminating upwardly in inturned flanges, said channel member being longitudinally slidingly engaged with said sole portion from one end thereof with said inturned flanges overlying upper surfaces of opposite side marginal portions of said lower sole portion.
Claim 12
