PROBLEM TO BE SOLVED: To make it possible to use shoes sweating preventive soles as soles as well, to use these soles alone as inner socks of shoes as well and to prevent the occurrence of athlete's feet and the generation of smells by passing air in the shoes. SOLUTION: Air is always accumulated between upper parts and lower parts by forming the soles 1 and 2 double and the air is passed by the movement of the feet. The soles 1 and 2 are double and pass the air in order of shanks and toes from heels by utilizing the movement in order of the heels, shanks and the toes at the time of walking. The soles are capable of keeping the air accumulated in the shanks from the toes when force is applied to the toes and the air is delivered.
