Abstract
Abstract A boot liner, preferably for use with a ski boot of the rear-entry type, including an exterior envelope and an interior sock, having an injection cavity therebetween. Within the injection cavity, a filling product is designed to be injected for retaining the foot of the skier within the boot liner and within the ski boot within which it is adapted to be used. The exterior envelope and the interior sock are sealed along a lower peripheral edge defining a sole portion of the boot liner. The peripheral edge is engageable within a peripheral groove in the internal wall of the exterior envelope to thereby seal the injection cavity from the sole portion of the boot liner to thereby prevent the filling product from flowing beneath the sole of the foot positioned within the boot liner. The injection cavity is defined by respective surfaces of the external envelope and the interior sock. The surface of the interior sock adjacent the cavity is coated with a anti-friction film which is micro-porous for permitting the escape of residual air within the cavity as the filling product is injected therein, while retaining the filling product. Further, the surface or the exterior envelope adjacent the cavity includes a plurality of peripheral ribs which direct the flow of the filling product from the injection orifice toward remote portions of the cavity. Maintenance means and foot retention means can be used in conjunction with the boot liner of the present invention.
