| 摘要 |
This invention concerns an insole for footwear, which is new in having an uneven upper surface, consisting of many high supporting areas (6) for foot sole, with a very high elastic modulus, and many low air passages (7), stretched to upper surface's edges (9). Under the upper surface, there is an elastic air chamber, connected to the air passages by many air canals (8). Under the foot's pressure, both the upper surface and the air chamber act as air pumps, pumping the air through air passages and out of upper surface's edges. This brings the surface of the foot sole, sock or stocking in direct contact with exchanged and moving air, which yields a drier, cleaner and healthier foot sole. Furthermore, the insole is suitable for shock absorption, fitting the shoe's size and shape to the foot, adjustment of the foot sole's pressure distribution, temperature regulation, and physiotherapic purposes. |
