The invention belongs to the technical field of mountaineering shoes, and in particular relates to mountaineering power-assisting shoes based on driving of a magnet universal joint. Each mountaineering power-assisting shoe comprises a drive mechanism, a pressure mechanism and an air storage tank. During the mountaineering process, the shoe uppers upwards incline relatively, at the time, swing teeth can incline backwards under the action of gravitation, under the effect of limiting teeth, the swing angles of sector-shaped teeth and the swing teeth are fixed, then the swing teeth and the ground form occlusion, and finally, the anti-skidding effect is achieved. Meanwhile, high-pressure air in the air storage tank flows into a power-assisting shell through a pressure air pipe, when contacting the ground, an power-assisting cylinder applies a downward pressure to the ground, so that the power-assisting shoes suffer from an upward action force, and thus the power assisting effect is achieved. When a wearer jumps, a magnetic push board moves downwards so as to generate a repelling force for magnets mounted at the upper end of a universal joint outer ring and the upper end of a universal joint middle ring, so that swing is seldom generated between the power-assisting shoe and the leg, and finally, the sprain-preventing effect is achieved.
