ABSTRACT:
There is provided a ski boot formed of plastic material and having a sole and a shaft consisting of a front shaft part having a shell and a rear shaft part articulated on the shell at the heel. The front shaft part is provided with zones of weakness in the arch and shin areas which increase the flexibility of the front shaft part in the longitudinal direction of the boot. Stiffening elements are provided in the zones of weakness extending transversely to the boot axis and having a variable effect on the flexibility of the front shaft part of the boot. The zones of weakness are formed by wave-like elevations and depressions on the front shaft part, the elevations projecting against the outer side of the boot so as to define hollow spaces sealed against the front side of the boot and accommodating therein the stiffening elements.
