<p><P>PROBLEM TO BE SOLVED: To improve the breathability by activating air inflow/outflow. <P>SOLUTION: The upper face of a lower sole 4 is formed with lateral grooves 5 reaching the side face of the sole 1, and the upper sole 3 formed with a recess part 7 is superposed on the lower sole 4. The recess part 7 is fitted with a block body 8 having elasticity and the upper part of the block body 8 projects upward from the upper face of the upper sole 3. The upper face of the lower sole 4 is disposed with a support sheet 9 having the breathability and supports the block body 8 in the recess part 7. The inside of the shoe and the lateral grooves 5 communicates with each other through vertical holes 10 of the block body 8 and the support sheet 9, and when a load is applied to the block body 8, the vertical holes 10 are deformed to cause the air inflow/outflow through the lateral grooves 5. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
