<p>PROBLEM TO BE SOLVED: To provide a shoe sole with which a foot does not get musty even after wearing for a long time. SOLUTION: This shoe sole is composed of a lower sole 1, middle sole 2 bonding its one side with the lower sole 1 while forming a plurality of space parts 6a, 6b and 6c, communicating holes 7a and 7b mutually among the space parts and communicating hole 8 between the space part 7a and external air, and upper sole 3 opening a plurality of communicating holes 9 through which the space parts 6a, 6b and 6c formed on the middle sole 2 communicate with a main body 5 of shoe, bonding its toe part onto the middle sole 2, forming an air chamber 11 by linking a gap with the outer form of middle sole 2 at the other section through elastic bellows 4, and constituting that air chamber so as to be disconnected from/connected to the middle sole 2 through the bellows 4. In this case, a back flow preventing valve 10 for sucking air and stopping exhaustion is disposed at the opening part of external air communicating hole 8 on the side of space part 7a.</p> |
