Abstract
Abstract A waterproof cross-country ski boot is provided with a soft, comfortable low-sided upper and a relatively solid nonflexible sole. The sole is configured to conform with the ski bindings and provide the required rigidity in the heel area while simultaneously allowing sufficient flexibility so that the boot may be worn as conventional sportswear. Moreover, provision is made for sufficient warmth in the boot upper, and the general interface between the boot upper and the sole is so configured to be watertight.
