PROBLEM TO BE SOLVED: To eliminate shortcomings wherein a conventional pair of shoes do not have a sufficient ventilation inside, and foot soles become stuffy due to perspiration, and a malodor is generated although various kinds of devices have been tried; and provide a pair of shoes, of which the wearing feeling is favorable and comfortable, having an excellent ventilation property by adopting functions for warming in a cold season, and for cooling in a hot season to eliminate the shortcomings. SOLUTION: When a human being walks or runs, toe base joint sections more or less bend, and the bending action is utilized for this pair of shoes. In this case, the arms 6 and 7 of a lever of which the fulcrum is the bending section is vertically moved by the bending action, and the motion of the triangle lever 8 is converted into a towing motion by the vertical motion. Then, the motion of a spindle (main shaft) 10 is converted into an inverting motion by a connector rod 9, and the motion of a fork rod 12 fixed to the spindle 10 is converted into a vertical motion. Then, a piston 41 is vertically moved by the fork rod 12, and thus, the shoes constituted in such a manner that fresh air is fed into the shoes from the outside are provided.
