The invention relates to a snowshoe and rucksack for its storage with an application in the sports sphere and in particular on snow covered and ice-frozen terrains. The inflatable snowshoe contains a corpus and fixing belts. The corpus consists of a cylindrical air chamber and protective case. The air chamber forms a closed contour having the form of an elliptical ring with a circular cross section and is placed in the protective case. The air chamber has a valve mounted on it the end of which passes through an opening formed in the rear part of the protective case. The protective case is made of separate sections of a strong, wear-resistant material. The frontal part of protective case contains three sections which are raised in relation to the horizontal axis under an angle of α, which falls within the interval between 35° to 40°. Over the entire internal circumference of protective case there is a zipper, ensuring quick and easy placing of the air chamber in casing. Fixing belts are provisioned respectively for the front and rear part of the shoe. To the lower part of the fixing belts for the frontal part of the surface metal spikes are mounted in a mobile way and they ensure a better grip of ice-frozen terrains. The rucksack has been especially designed for the storage of the snowshoe in its inflated state and under given conditions it also plays the role of a back protector. The profile of the rucksack corresponds completely to the profile of the snowshoe.
An inflatable snowshoe, including a corpus and fixing belts for a frontal part of a shoe, where the corpus is a cylindrical air chamber forming a closed contour, and an air valve is mounted on an air chamber, wherein the closed contour, formed by the air chamber (1) has the form of an elliptical ring with circular cross section where the air chamber (1) is placed in a protective case (2) with a cylindrical profile, made of a strong wear-resistant material, where the protective case (2) is formed in separate sections (A,B,C,D,E,F,G) having different lengths, immovably connected one to another where three of the sections (A,B,C) forming a frontal part of the protective case (2) are raised relative to a horizontal axis under an angle of α, while the entire interior circumference of the protective case (2) has a zipper (3) for access to the air chamber (1) and fixing belts (4a) for the frontal part of the shoe are immovably mounted sideways and in the frontal part of the exterior surface of the protective case (2) under a level of the zipper (3), where to a lower part of the fixing belts (4a) for a frontal part of a shoe metal spikes (9) are movably attached, whereupon at a rear part and sideways to an exterior surface of the protective case (2) under the level of the zipper (3) fixing belts (4b) are permanently fixed for a heel of the shoe, and in the rear part of the protective case (2) an opening has been made (10) which holds the end nozzle (11) of the air valve (6).
