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.
